| 1 | Application of next-generation sequencing technology to precision medicine in cancer: joint consensus of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology显示文摘Next-generation sequencing(NGS) technology is capable of sequencing millions or billions of DNA molecules simultaneously.Therefore, it represents a promising tool for the analysis of molecular targets for the initial diagnosis of disease, monitoring of disease progression, and identifying the mechanism of drug resistance. On behalf of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology(CSCO) and the China Actionable Genome Consortium(CAGC), the present expert group hereby proposes advisory guidelines on clinical applications of NGS technology for the analysis of cancer driver genes for precision cancer therapy. This group comprises an assembly of laboratory cancer geneticists, clinical oncologists, bioinformaticians,pathologists, and other professionals. After multiple rounds of discussions and revisions, the expert group has reached a preliminary consensus on the need of NGS in clinical diagnosis, its regulation, and compliance standards in clinical sample collection. Moreover, it has prepared NGS criteria, the sequencing standard operation procedure(SOP), data analysis, report, and NGS platform certification and validation. | Xuchao Zhang Zhiyong Liang Shengyue Wang Shun Lu Yong Song Ying Cheng Jianming Ying Weiping Liu Yingyong Hou Yangqiu Li Yi Liu Jun Hou Xiufeng Liu Jianyong Shao Yanhong Tai Zheng Wang Li Fu Hui Li Xiaojun Zhou Hua Bai Mengzhao Wang You Lu Jinji Yang Wenzhao Zhong Qing Zhou Xuening Yang Jie Wang Cheng Huang Xiaoqing Liu Xiaoyan Zhou Shirong Zhang Hongxia Tian Yu Chen Ruibao Ren Ning Liao Chunyan Wu Zhongzheng Zhu Hongming Pan Yanhong Gu Liwei Wang Yunpeng Liu Suzhan Zhang Tianshu Liu Gong Chen Zhimin Shao Binghe Xu Qingyuan Zhang Ruihua Xu Lin Shen Yilong Wu | 2019 | Cancer Biology & Medicine2019,16,1: | 14 |
| 2 | SHRIMP zircon age for a K-bentonite in the top of the Laobao Formation at the Pingyin section,Guizhou,South China显示文摘The Lower Cambrian on the Yangtze Platform in South China(internationally equivalent to the Nerreneuvian and 2nd series of the Cambrian)is valuable for understanding the early evolution of life,the global biogeochemical circles,and the major changes of the ocean.In particular,a precise radiometric calibration of the Lower Cambrian of this region is a critical realm in its multidisciplinary studies.A SHRIMP U-Pb geochronology study of the K-bentonite in the topmost Laobao Formation at the Pingyin section,Guizhou,South China yielded an age of 536±5 Ma(MSWD=0.75),suggesting that the K-bentonite here can be correlated with the intensely studied K-bentonite within the middle Zhongyicun Member(Bed 5)of the Zhujiaqing Formation at the Meishucun section in Yunnan.Such a regional correlation result reveals that the Bed 5 K-bentonite also extends into deeper-water environments rather than being deposited merely in the shallow platform interior of the Yangtze Platform.The age of the K-bentonite at the Pingyin section also implies that its overlying polymetallic Ni-Mo layer should be younger than 536±5 Ma.Hence the previous placement of the Precambrian/Cambrian boundary at this layer is inappropriate.Combined with the results of stratigraphic correlations,it is suggested that the K-bentonites in the middle Zhongyicun Member of the Zhujiaqing Formation(or the equivalents)and the base of the Shiyantou Formation(or its equivalents),together with the polymetallic Ni-Mo layer,serve as three important marker beds.Their self-consistent radiometric ages have established an improved geochronologic framework for the Lower Cambrian in South China. | ZHOU MingZhong LUO TaiYi LIU ShiRong QIAN ZhiKuan XING LeCai | 2013 | Science China Earth Sciences2013,56,10: | 10 |
| 3 | Variation of carbon and nitrogen stoichiometry along a chronosequence of natural temperate forest in northeastern China显示文摘Aims Carbon(C)and nitrogen(N)stoichiometry contributes to under-standing elemental compositions and coupled biogeochemical cycles in ecosystems.However,we know little about the temporal patterns of C:N stoichiometry during forest development.The goal of this study is to explore the temporal patterns of intraspecific and ecosystem components’variations in C:N stoichiometry and the scaling relationships between C and N at different successional stages.Methods Along forest development in a natural temperate forest,northeastern China,four age gradients were categorized into ca.10-,30-,70-and 200-year old,respectively,and three 20 m×20 m plots were set up for each age class.Leaves,branches,fine roots and fresh litter of seven dominant species as well as mineral soil at depth of 0-10 cm were sampled.A Universal CHN Elemental Analyzer was used to determine the C and N concentrations in all samples.Important Findings Intraspecific leaf C,N and C:N ratios remained stable along forest development regardless of tree species;while C,N concentrations and C:N ratios changed significantly either in branches or in fine roots,and they varied with tree species except Populus davidiana(P<0.05).For ecosystem components,we discovered that leaf C:N ratios remained stable when stand age was below ca.70 years and dominant tree species were light-demanding pioneers such as Betula platyphylla and Populus davidiana,while increased signifi-cantly at the age of ca.200 years with Pinus koraiensis as the dom-inant species.C:N ratios in branches and fresh litter did not changed significantly along forest development stages.C concentrations scaled isometrically with respect to N concentrations in mineral soil but not in other ecosystem components.Our results indicate that,leaf has a higher intraspecific C:N stoichiometric stability compared to branch and fine root,whereas for ecosystem components,shifts in species composition mainly affect C:N ratios in leaves rather than other components.This study also demonstrated that C and N remain coupled in mineral soils but not in plant organs or fresh litter during forest development. | Xingyun Liang Shirong Liu Hui Wang Jingxin Wang | 2018 | Journal of Plant Ecology2018,11,3: | 9 |
| 4 | Trade-offs and Synergies of Ecosystem Services in Karst Area of China Driven by Grain-for-Green Program显示文摘As an important means regulating the relationship between human and natural ecosystem,ecological restoration program plays a key role in restoring ecosystem functions.The Grain-for-Green Program(GFGP,One of the world’s most ambitious ecosystem conservation set-aside programs aims to transfer farmland on steep slopes to forestland or grassland to increase vegetation coverage)has been widely implemented from 1999 to 2015 and exerted significant influence on land use and ecosystem services(ESs).In this study,three ecological models(In VEST,RUSLE,and CASA)were used to accurately calculate the three key types of ESs,water yield(WY),soil conservation(SC),and net primary production(NPP)in Karst area of southwestern China from 1982 to 2015.The impact of GFGP on ESs and trade-offs was analyzed.It provides practical guidance in carrying out ecological regulation in Karst area of China under global climate change.Results showed that ESs and trade-offs had changed dramatically driven by GFGP.In detail,temporally,SC and NPP exhibited an increasing trend,while WY exhibited a decreasing trend.Spatially,SC basically decreased from west to east;NPP basically increased from north to south;WY basically increased from west to east;NPP and SC,SC and WY developed in the direction of trade-offs driven by the GFGP,while NPP and WY developed in the direction of synergy.Therefore,future ecosystem management and restoration policy-making should consider trade-offs of ESs so as to achieve sustainable provision of ESs. | WANG Xiaofeng ZHANG Xinrong FENG Xiaoming LIU Shirong YIN Lichang CHEN Yongzhe | 2020 | Chinese Geographical Science2020,30,1: | 8 |
| 5 | Cloning and functional characterization of Rht8,a“Green Revolution”replacement gene in wheat显示文摘Dear Editor,Wheat(Triticum aestivum)is a major staple crop in the world and provides~20%of the food calories for human consumption(Appels et al.,2018).During the 1960s and 1970s,the introduction of two semi-dwarfing genes Rht-B1b and Rht-D1b in wheat varieties strikingly improved lodging resistance and harvest index,and therefore substantially increased grain yield,resulting in the well-known'Green Revolution'(Peng et al.,1999).However,plants carrying Rht-B1b and Rht-D1b suffer from several drawbacks. | Hongchun Xiong Chunyun Zhou Meiyu Fu Huijun Guo Yongdun Xie Linshu Zhao Jiayu Gu Shirong Zhao Yuping Ding Yuting Li Jiazi Zhang Ke Wang Xuejun Li Luxiang Liu | 2022 | Molecular Plant2022,15,3: | 7 |
| 6 | Study on Biotribological Behavior of the Combined Joint of CoCrMo and UHMWPE/BHA Composite in a Hip Joint Simulator显示文摘UHMWPE composites reinforced with Bovine Bone Hydroxyapatite(BHA)in different contents were prepared by heatpressing formation method.A hip joint wear simulator was used to investigate the biotribological behavior of UHMWPE/BHAcomposite acetabular cups against CoCrMo alloy femoral heads in bovine synovia lubrication at 37±1 ℃.It was found that theaddition of BHA powder to UHMWPE can improve the hardness and creep modulus of UHMWPE/BHA composites,anddecrease their wear rates under bovine synovia lubrication.When the content of BHA filler particles was up to 30 wt%,UHMWPE/BHA composites demonstrated the well design performances of the surface and biotribological properties.Fatigue,ploughing and slight adhesive wear were the main wear mechanisms for UHMWPE and its composites.In addition,the sizes ofwear particles became larger with an increase in BHA powder addition.These results suggest that BHA filler is a desirablecomponent to increase the wear resistance of UHMWPE/BHA composites for biomedical applications. | Qingliang Wang, Jinlong Liu, Shirong GeCollege of Materials and Engineering, China University of Mining and Technology, Xuzhou 221007, P.

| 7 | Variations in leaf litter decomposition across contrasting forest stands and controlling factors at local scale显示文摘Aims litter decomposition is a critical pathway linking the above-and belowground processes.However,factors underlying the local spatial variations in forest litter decomposition are still not fully addressed.We investigated leaf litter decomposition across con-trasting forest stands in central China,with objective to determine the spatial variations and controlling factors in forest floor leaf lit-ter decomposition in relation to changes in forest stands in a tem-perate forest ecosystem.Methods leaf litter decomposition was studied by using litterbag method across several typical forest stand types in baotianman Nature reserve,central China,including pure stands of Quercus aliena var.acuteserrata,Q.glandulifera var.brevipetiolata and Q.vari-abilis,respectively,and mixed pine/oak stands dominated by Pinus armandii and Q.aliena var.acuteserrata,as well as stands of pure Q.aliena var.acuteserrata trees ranging in stand age from~40 to>160 years.measurements were made on litter mass remaining and changes in litter chemistry during decomposition over a 2-year period,along with data collections on selective biotic and environmental factors.a reciprocal transplant experiment involv-ing Q.aliena var.acuteserrata and Q.variabilis was concurrently carried out to test the occurrence of‘home-field advantage(HFa)’in local forests when only considering contrasting oak tree spe-cies.Correlation analyses and path analyses were performed to identify the dominant drivers and their relative contributions to variations in leaf litter decomposition.Important findingssignificant variations were found in the rate of leaf litter decomposi-tion among stands of different tree species but not among stand age classes.The values of decay constant,k,varied from 0.62 in Q.aliena var.acuteserrata stands to 0.56 in Q.variabilis stands.The reciprocal litter transplant experiment showed that the rate of leaf litter decom-position was on average 5%slower in home-fields than on recipro-cal sites.Path analysis identified litter acid-unhydrolyzable residue(AUR)to N ratio,soil microbial biomass carbon(MBC),soil pH and soil organic carbon(SOC)as most prominent factors controlling the rate of leaf litter decomposition,collectively accounting for 57.8%of the variations;AUR/N had the greatest negative effect on k value,followed by weaker positive effects of SOC and MBC.our findings suggest that tree species plays a primary role in affecting forest floor leaf litter decomposition by determining the litter quality,with site environment being a secondary factor contributing to the local vari-ations in leaf litter decomposition in this temperate forest ecosystem. | Juan Wang Yeming You Zuoxin Tang Shirong Liu Osbert Jianxin Sun | 2015 | Journal of Plant Ecology2015,8,3: | 6 |
| 8 | Preparation and properties of a new cutting pick of coal shearers显示文摘Reliability and wear resistance of cutting picks play a significant role in coal mine exploitation with coal shearers.Tool bit separation,blade breaking,severe erosion of the cutting body and fatigue fractures are the main reasons for failure of cutting picks.We carried out carburization on a 30CrMnMo alloy to synthesize a new cutting pick material with improved mechanical properties and high wear resistance.The results indicated that carburization can effectively strengthen the surface of the 30CrMnMo alloy by forming a thick carburized layer and thus significantly improve the surface hardness and wear resistance.In addition,the excellent toughness of 30CrMnMo alloy as a substrate of cutting picks can prevent brittle ruptures and fatigue fractures under high impact stress conditions.The significant decrease in both frictional coefficient and rate of erosion of this carburized 30CrMnMo alloy suggests that this alloy is a potential material for cutting picks of coal shearers after rational carburization. | LUO Yong ZHANG Dekun WANG Qingliang LIU Hongtao CHENG Gang GE Shirong | 2010 | Mining Science and Technology2010,20,5: | 5 |

| 10 | Nutrient resorption strategies of three oak tree species in response to interannual climate variability显示文摘Background:Nutrient resorption is critical for plants toward balancing their nutritional requirements and adapting to environmental variabilities,which further impacts litter quality and nutrient cycling.However,the interannual variability of nutrient resorption under climate change remains unclear.Methods:We investigated the five-year nutrient resorption efficiencies(NuRE,%)of 14 elements in three deciduous oak tree species(Quercus aliena var.acuteserrata,Q.glandulifera,and Q.variabilis)in a warm-temperate forest of Central China and assessed their relationships with interannual climate and soil factors.Results:Nutrient resorption did not differ between species but varied significantly between different years.For each year,N,P,S,K,C,Mg,and Zn were preferentially resorbed in all of the oak species in contrast to Ca,Na,Mn,Ba,Al,Fe,Cu,which were to some extent discriminated.Among the 14 elements,the NuRE of C,N,P,S,Ca,and Mg was more sensitive to interannual climate variations in the three oak species.The carbon resorption efficiency was significantly increased during the driest year of the study(2014);N resorption efficiency was reduced with temperature;whereas N and P resorption efficiency initially decreased and then increased with precipitation.Moreover,the elements with higher NuREs typically had lower coefficient of variation(CV)in all three oak species.Conclusions:Different oak species exhibited analogous nutrient conservation strategies in response to annual climate variabilities,and interannual climate variations strongly impacted plant nutrient resorption.Deciduous plants may establish a tradeoff mechanism to rebalance somatic nutrients for regrowth at the end of the growing season. | Baoming Du Huawei Ji Shirong Liu Hongzhang Kang Shan Yin Chunjiang Liu | 2021 | Forest Ecosystems2021,8,4: | 4 |
| 11 | Reconciliation of research on forest carbon sequestration and water conservation显示文摘Carbon sequestration and water conservation are two of the key ecosystem services that forests provide for societal need to address environmental issues.Optimization of the dual services is the ultimate goal in forest management for mitigating global climate change and safeguarding terrestrial water balance.However,there are some tradeoff s between gain in forest productivity and ecosystem water balance.We conducted literature review based on published articles for learned knowledge on forest carbon fi xation and hydrological regulations.Some knowledge gaps and research needs are identifi ed by examining the inter-connections between forest carbon sequestration and water conservation.Past researches have helped gain basic understanding of the mechanisms and controls of forest carbon fi xation and hydrological regulations as two separate issues.Tools and approaches are well established for quantifying and monitoring forest carbon and hydrological issues,operating at diff erent spatial and temporal scales.There are knowledge gaps on how to design aff orestation schemes facilitating enhanced ecosystem services in forest carbon sequestration and water conservation.For the top-down planning of aff orestation in regions where water availability is anticipated to be problematic,the questions of how much and where to plant for given land availability,known environmental implications,and sustained regional development and livelihood need to be addressed.For local management considerations,the questions of what and how to plant prevail.Eff orts are needed in joint studies of forest carbon sequestration and water conservation functionalities,specifi cally in relation to establishment and management of planted forests aiming for delivering regulatory ecosystem services in carbon sequestration,water conservation and other social values.We propose an integrated framework with dual consideration of carbon sequestration and water conservation in forest management for future research pursue. | Tanzeel Javaid Aini Farooqi Xuhua Li Zhen Yu Shirong Liu Osbert Jianxin Sun | 2021 | Journal of Forestry Research2021,32,1: | 4 |
| 12 | Molecular breeding of water lily: engineering cold stress tolerance into tropical water lily显示文摘Water lilies(order Nymphaeales)are rich in both economic and cultural values.They grow into aquatic herbs,and are divided into two ecological types:tropical and hardy.Although tropical water lilies have more ornamental and medicinal values compared to the hardy water lily,the study and utilization of tropical water lilies in both landscaping and pharmaceutical use is greatly hindered due to their limited planting area.Tropical water lilies cannot survive the winter in areas beyond 24.3°N latitude.Here,the transgenic pipeline through the pollen-tube pathway was generated for water lily for the first time.To improve cold stress tolerance of tropical water lilies,a gene encoding choline oxidase(CodA)driven by a cold stress-inducible promoter was transformed into a tropical water lily through the pollen-tube transformation.Six independent transgenic lines were tested for survival rate during two winter seasons from 2015 to 2017 in Hangzhou(30.3°N latitude).PCR and southern blot detection revealed that the CodA gene had been integrated into the genome.Reverse transcription PCR showed that CodA gene was induced after cold stress treatment,and further quantitative real-time PCR revealed different expressions among six 4 lines and line 3 had the highest expression.Multiple physiological experiments showed that after cold stress treatment,both the conductivity and malondialdehyde(MDA)levels from transgenic plants were significantly lower than those of non-transgenic plants,whereas the content of betaine and the activity of superoxide dismutase,catalase,and peroxidase were higher than those from non-transgenic plants.These results suggest that expression of exogenous CodA gene significantly improved the cold stress tolerance of tropical water lilies through a wide range of physiological alterations.Our results currently expanded a six-latitude cultivating area of the tropical water lilies.These results not only illuminate the bright future for water lily breeding but will also facilitate the functional genomic studies. | Cuiwei Yu Guirong Qiao Wenmin Qiu Dongbei Yu Shirong Zhou Yan Shen Guanchun Yu Jing Jiang Xiaojiao Han Mingying Liu Liangsheng Zhang Fei Chen Yuchu Chen Renying Zhuo | 2018 | Horticulture Research2018,5,1: | 4 |

| 14 | Integrated watershed management:evolution,development and emerging trends显示文摘Watershed management is an ever-evolving practice involving the management of land,water,biota,and other resources in a defined area for ecological,social,and economic purposes.In this paper,we explore the following questions:How has watershed management evolved? What new tools are available and how can they be integrated into sustainable watershed management? To address these questions,we discuss the process of developing integrated watershed management strategies for sustainable management through the incorporation of adaptive management techniques and traditional ecological knowledge.We address the numerous benefits from integration across disciplines and jurisdictional boundaries,as well as the incorporation of technological advancements,such as remote sensing,GIS,big data,and multi-level social-ecological systems analysis,into watershed management strategies.We use three case studies from China,Europe,and Canada to review the success and failure of integrated watershed management in addressing different ecological,social,and economic dilemmas in geographically diverse locations.Although progress has been made in watershed management strategies,there are still numerous issues impeding successful management outcomes;many of which can be remedied through holistic management approaches,incorporation of cutting-edge science and technology,and cross-jurisdictional coordination.We conclude by highlighting that future watershed management will need to account for climate change impacts by employing technological advancements and holistic,cross-disciplinary approaches to ensure watersheds continue to serve their ecological,social,and economic functions.We present three case studies in this paper as a valuable resource for scientists,resource managers,government agencies,and other stakeholders aiming to improve integrated watershed management strategies and more efficiently and successfully achieve ecological and socio-economic management objectives. | Guangyu Wang Shari Mang Haisheng Cai Shirong Liu Zhiqiang Zhang Liguo Wang John L.Innes | 2016 | Journal of Forestry Research2016,27,5: | 4 |
| 15 | Erythromycin loaded by tetrahedral framework nucleic acids are more antimicrobial sensitive against Escherichia coli(E.coli)显示文摘Erythromycin is a commonly used broad-spectrum antibiotic,but resistance to this antibiotic makes its use less effective.Considerable efforts,beside finding alternatives,are needed to enhance its antimicrobial effect and stability against bacteria.Tetrahedral framework nucleic acids(tFNAs),a novel delivery vehicle with a three-dimensional nanostructure,have been studied as a carrying platform of antineoplastic drugs.In this study,the use of tFNAs in delivering erythromycin into Escherichia coli(E.coli)was investigated for the first time.The tFNAs vehicle increased the bacterial uptake of erythromycin and promoted membrane destabilization.Moreover,it increased the permeability of the bacterial cell wall,and reduced drug resistance by improving the movement of the drug across the membrane.The tFNAs-based delivery system enhanced the effects of erythromycin against E.coli.It may therefore provide an effective delivery vehicle for erythromycin in targeting antibiotic-resistant bacteria with thick cell wall. | Yue Sun Yuhao Liu Bowen Zhang Shirong Shi Tao Zhang Dan Zhao Taoran Tian Qirong Li Yunfeng Lin | 2021 | Bioactive Materials2021,6,8: | 4 |
| 16 | Characteristics of typhoon disturbed gaps in an old-growth tropical montane rainforest in Hainan Island, China显示文摘Disturbances that create gaps can shape the structure and function of forests. However, such disturbance regimes in Asian tropical montane rainforests remain largely unquantified. Least studied are typhoon disturbances that are attributable to climate change. We investigated gap characteristics in terms of size, age, and gapmaker to quantify the gap disturbance regimes in an intact old-growth tropical montane rainforest on Hainan Island,China. The intensity of typhoons has increased since 1949,and typhoon winds blow mostly(45.5%) from the northeast corner of Hainan Island, resulting in a higher frequency of gaps in the northeast. A total of 221 gap-makers(trees that fell to create canopy gaps) and 53 gaps were observed in a 3.16 ha old-growth rainforest. Most canopy gaps(85%)were <200 m^2. The average size of canopy gaps was smaller in the rainforest than in other tropical forests, while the average size of expanded gaps was similar to those in other tropical forests. The maximum age of gaps was 23.5 years indicating that gaps had more rapid turnover than other parts of tropical forests. The frequency distribution of gap-makers followed a lognormal distribution with a distinctive peak at three gap-makers, which was different from the inverse J-shaped curve typical of other tropical forests. Gaps were recorded mainly on slopes between 20° and 35° and wood density of gap-makers was between 0.6 and 0.7 g cm^(-3). Our results suggest that small-scale disturbance was the dominant agent of gap formation in this old-growth rainforest that is subject to increasing typhoon disturbances. | Huai Yang Shirong Liu Kunfang Cao Jingxin Wang Yide Li Han Xu | 2017 | Journal of Forestry Research2017,28,6: | 3 |
| 17 | Forest management required for consistent carbon sink in China’s forest plantations显示文摘Background:Forest is the largest biomass carbon(C)pool in China,taking up a substantial amount of atmospheric carbon dioxide.Although it is well understood that planted forests(PFs)act as a large C sink,the contribution of human management to C storage enhancement remains obscure.Moreover,existing projections of forest C dynamics suffer from spatially inconsistent age and type information or neglected human management impacts.In this study,using developed PF age and type maps and data collected from 1371 forest plantation sites in China,we simulated biomass C stock change and quantified management impacts for the time period 2010-2050.Results:Results show that future forest biomass C increment might have been overestimated by 32.5%-107.5% in former studies.We also found that age-related growth will be by far the largest contributor to PF biomass C increment from 2010 to 2050(1.23±0.002 Pg C,1 Pg=10^(15) g=1 billion metric tons),followed by the impact of human management(0.57±0.02 Pg C),while the contribution of climate is slight(0.087±0.04 Pg C).Besides,an additional 0.24±0.07 Pg C can be stored if current PFs are all managed by 2050,resulting in a total increase of 2.13±0.05 Pg C.Conclusions:Forest management and age-related growth dominate the biomass C change in PFs,while the effect of climatic factors on the accumulation is minor.To achieve the ambitious goal of forest C stock enhancement by 3.5 Pg from 2020 to 2050,we advocate to improve the management of existing forests and reduce the requests for more lands for forest expansion,which helps mitigate potential conflicts with agricultural sectors.Our results highlight that appropriate planning and management are required for sustaining and enhancing biomass C sequestration in China’s PF. | Zhen Yu Weibin You Evgenios Agathokleous Guoyi Zhou Shirong Liu | 2021 | Forest Ecosystems2021,8,4: | 3 |

| 19 | Adaptation of Asia-Pacific forests to climate change显示文摘Climate change is a threat to the stability and productivity of forest ecosystems throughout the AsiaPacific region. The loss of forests due to climate-induced stress will have extensive adverse impacts on biodiversity and an array of ecosystem services that are essential for the maintenance of local economies and public health. Despite their importance, there is a lack of decision-support tools required to evaluate the potential effects of climate change on Asia-Pacific ecosystems and economies and to aid in the development of regionally appropriate adaptation and mitigation strategies. The project Adaptation of AsiaPacific Forests to Climate Change, summarized herein,aims to address this lack of knowledge and tools and to provide support for regional managers to develop effective policy to increase the adaptive capacity of Asia-Pacific forest ecosystems. This objective has been achieved through the following activities:(1) development of a highresolution climate downscaling model, Climate AP, applicable to any location in the region;(2) development of climate niche models to evaluate how climate change might affect the distribution of suitable climatic conditions for regionally important tree species;(3) development and application of forest models to assess alternative management strategies in the context of management objectives and the projected impacts of climate change;(4) evaluation of models to assess forest fire risk and the relationship between forest fire and climate change;(5) development of a technique to assess ecosystem carbon storage using Li DAR; and(6) evaluation of how vegetation dynamics respond to climate change using remote sensing technology. All project outputs were developed with a focus on communication and extension to facilitate the dissemination of results to regional forest resource managers to support the development of effective mitigation and adaptation policy. | Guangyu Wang Tongli Wang Haijun Kang Shari Mang Brianne Riehl Brad Seely Shirong Liu Futao Guo Qinglin Li John L.Innes | 2016 | Journal of Forestry Research2016,27,3: | 2 |
| 20 | Optimization of shearer sliding boots by plasma cladding with Cr_4MnTi显示文摘Severe production conditions in coal mines cause damage and failure problems with the oriented sliding boots of the mechanical shearer. Wear has been an especially vexing problem. Plasma cladding methods were used to study optimized sliding boot design. By cladding the substrate steel the surface may be made of a material more resistant to wear. The iron based alloy Cr4MnTi was coated onto a modified 45 steel matrix material in these tests. The results show that the alloy cladding layer is high strength, has high hardness, and is highly resistant to wear. After hardening and tempering, 45 steel substrate has great tenacity so the combined structure meets the performance requirements for the construction of shearer sliding boots. | Liu Hongtao Wang Luping Ge Shirong Cao Shoufan Jin Jing Gao Jiping | 2011 | Mining Science and Technology2011,21,6: | 2 |
