1基于遥感和GIS的巢湖流域生态功能分区研究显示文摘生态功能分区是区域自然资源科学管理及可持续发展利用的基础。基于生态功能分区原则,考虑流域——子流域完整性进行巢湖流域生态功能分区。在综合分析巢湖流域生态环境基本特征的基础上,确定生态功能分区原则、依据、方法及命名,基于遥感与GIS在数据采集方面及多层面叠加功能的优势,通过遥感数据对研究区土地利用信息的提取以及利用DEM空间分析进行子流域划分等技术手段,探讨了遥感和GIS技术支持下的研究区子流域生态功能划分方法,形成了巢湖流域生态功能分区方案,将全流域分为5个生态功能区和12个生态功能亚区,并阐明了不同生态功能区的生态保护重点与经济社会发展约束。对于新调整行政区划的巢湖流域生态环境综合治理具有重要的现实意义,可为流域产业布局、生态防灾减灾、环境保护与建设规划等提供科学依据。王传辉 吴立 王心源 王官勇 孙叶根 胡降临 2013生态学报2013,33,18:38
2江汉平原钟桥遗址地层揭示的史前洪水事件显示文摘通过野外考古调查研究,利用对钟桥遗址疑似古洪水层和研究区现代洪水沉积物的锆石微形态、粒度、磁化率、Rb/Sr等地球化学指标的比较、AMS14C技术和考古器物断代,发现钟桥遗址在4800~4597 cal.a BP、4479~4367 cal.a BP和4168~3850 cal.a BP分别经历了三次古洪水事件并相应堆积了古洪水沉积层;结合江汉平原及其周边地区众多遗址的古洪水沉积层时代对比证据,揭示了屈家岭文化中晚期(4900~4600 cal.a BP)和石家河文化末期至夏代(4100~3800 cal.a BP)两次大洪水事件在江汉平原地区非常普遍。对史前洪水发生环境背景的进一步分析,反映江汉平原在5000~4500 a BP及4000 a BP前后的时段气候表现得不稳定,古洪水事件与气候环境变化驱动的江汉平原湖群扩张存在一定的联系,并影响区域新石器文化兴衰过程。同时,其它证据也表明该区社会发展过程和环境变化过程特别是古水文过程的矛盾在石家河文化末期已特别突出,发现具有全球意义的4000 a BP前后气候异常引起的大洪水事件是江汉平原地区石家河文化消亡的重要环境因素;而石家河文化末期该区内部或同中原以及其它地区间的冲突,都加速了石家河文化的崩溃。这些研究成果,提供了可靠的大禹时代史前洪水证据来说明其对新石器文化兴衰的社会影响,对于揭示4000 a BP气候事件中区域气候水文变化的响应规律,亦具有重要的科学意义。吴立 朱诚 李枫 马春梅 李兰 孟华平 刘辉 王晓翠 谭艳 宋友桂 2015地理学报2015,70,7:13
3莱州湾南岸中全新世聚落遗址时空分布特征及其环境背景显示文摘基于Arc GIS10.3平台对莱州湾南岸中全新世聚落遗址的高程、坡度、坡向、濒河度等指标进行分析,得出该时期聚落遗址的时空分布及演变特征,并结合全新世莱州湾南岸的环境背景,探讨全新世环境演变对聚落遗址分布及演变的影响。研究表明:(1)全新世莱州湾南岸的聚落遗址数量、出现频率及在总数中的比重基本呈现明显的先增后降的倒V型(非对称)变化趋势。(2)遗址高程分布具有一定的规律性,几乎所有时期的遗址点均分布于高程范围在0-29 m的地区,而大汶口文化时期遗址高程分布范围为10-29 m。从坡度来看,聚落遗址主要分布于坡度范围在0-4°的平缓地区;从坡向来看,古人大多集中在南向、东南向和西南向的位置。后李文化至龙山文化时期,河流对聚落选址的影响程度逐渐降低。(3)8.5-6.9 ka B.P.气候总体进入温暖期,且冷暖波动,干湿交替,后李文化由此得到发展;6.9-4.5 ka B.P.出现了短暂的降温,但整体较温和,优越的自然条件促进了大汶口文化的发展;4.5-4.0 ka B.P.左右气候条件较大汶口文化时期略干,但在此基础上新石器文化仍得到进一步发展,并于龙山文化时期进入鼎盛阶段;4.0 ka B.P.左右气候突变,出现剧烈降温事件,变化幅度超出了人类的适应能力,岳石文化随之衰落。(4)海水入侵限制了人类活动,而古湖泊和古河道的形成为古人生活质量的提高创造了天然条件。赵强 邹春辉 王爽 高倩 2018地理科学2018,38,9:8
4巢湖东部含山凌家滩遗址地层元素地球化学特征研究显示文摘通过对安徽巢湖东部含山凌家滩遗址的野外调查、地层采样和元素地球化学分析,结合年代学和文物考古成果,综合研究表明:1)元素迁移的剖面特征总体反映了凌家滩遗址地层由下至上脱硅富铝铁程度渐弱的趋势,符合亚热带地区风化成土的脱硅富铝化过程及特征;2)晚更新世末堆积的红褐色黏土层顶部是凌家滩人生活的古地貌面,早中全新世沉积速率较低,一方面与适宜期高温高湿的气候条件有关,另一方面也与间歇性的构造抬升运动有关;汉代和明清时期,由于受到晚全新世气候向干冷变化的影响,发生了一定规模的风成堆积;明清文化层虽然受到人类活动的影响,但在元素地球化学特征上依然反映出气候变化的因素;3)凌家滩遗址剖面下部的晚更新世沉积地层是以粉尘、风化型黏土为母质的风化层,它的特征介于下蜀黄土和风化壳黏土之间;遗址地层晚更新世沉积的岩性和化学组成代表的风化强度都超过了该区正常的下蜀黄土地层和其中的弱古土壤层。吴立 王心源 莫多闻 周昆叔 管后春 朱诚 2015地层学杂志2015,39,4:8
5Impact of Holocene climate change on the prehistoric cultures of Zhejiang region, East China显示文摘自从在浙江区域的 Holocene 比较地基于 GIS 空间分析被分析,时间空间的分发史前的文化展示。结果证明史前的文化在 4000 cal 前在这个区域逐渐地膨胀了。BP。著名扩大发生了两次,在 Majiabang-Hemudu 文化时期的,其它在 Liangzhu 文化时期。同时,史前的文化沿着河山谷从西方被传播到东方海岸。在 4000 cal 以后。BP 由 Maqiao 文化代表了每种史前的文化的分布式的区域收缩了。这显然由于散布趋势到东方海岸的结束,它被生产和经济转变的二个不同模式同时分别地在北方和南方浙江区域伴随。在史前的文化地点的分发变化被海平面的变化极大地影响的地方,史前的文化的分发与 Holocene 海平面的变化是密切相关的,特别在 Hangzhou 海湾的河岸上,在他们之间的最靠近的关系地。在 7000 cal 以后。BP,这个过程降低海平面并且 regression-epeirogenesis 为史前的居民提供了更宽的陆上的生活空格。基于史前的文化和在华东海的内部架上在塔恩穆山和泥泞区域的 Qianmutian 亚高山带的泥炭记录的环境进化信息的变化的比较分析,史前的文化的变化在浙江与环境变化被同步,这被显示区域。在 4000 cal 前。BP,史前的文化在的东方扩大浙江在 Holocene 最佳的背景下面发生了,并且在农业文明和海上的文明的联合影响下面是扩大和延期。然而,在 4000 cal 以后。BP,在浙江的史前的文化的地理收缩发生在干燥寒冷的气候趋势的背地面和沿海的海洋的环境的恶化下面。它从史前的文化的发展,扩大和收缩断然被相关到环境变化的上述事实被证实。气候的环境的变化只是为生产模式和经济形式的这些变化和转变的内在的原因。因此,气候的环境是在浙江区域的史前的文化变化的主导的因素,它对文化的分发,传播,扩大和变化施加了大影响。WU Li ZHU Cheng ZHENG Chaogui MA Chunmei WANG Xinhao LI Feng LI Bing LI Kaifeng 2014Journal of Geographical Sciences2014,24,4:8
6长江三角洲锦溪地区全新世气候适宜期孢粉组合及其环境意义显示文摘通过对长江三角洲锦溪地区白莲湖附近人工剖面的孢粉研究,重建该地区7 230cal a BP前后的植被和气候。孢粉植物群反映当时气候略有波动,但整体上与全新世气候适宜期的温暖环境相一致。孢粉自下而上可以细分为4个组合带:Zone 1青冈栎含量丰富,反映温暖气候;Zone 2落叶栎有所增多,气候稍有转凉;Zone 3青冈栎含量再度增高,气候变暖;Zone 4松属和落叶栎明显增多,气候再度转凉。从沟鞭藻和相关孢粉类型的分布分析,除底部12号样品因孢粉含量低而未予考虑外,其它样品都指示沉积时期当地受到海水的影响。其中Zone 1和Zone 2孢粉植物群指示两次海水的进退过程。当前孢粉研究结果很好地反映出长江三角洲地区全新世大暖期的气候变化特征,以及与当时海平面变化的关联。孟玉婷 王伟铭 李保华 丁金龙 2014古生物学报2014,53,2:6
7New Early Cretaceous Pterosaur-Bird Track Assemblage from Xinjiang, China:Palaeoethology and Palaeoenvironment显示文摘A pterosaur-bird track assemblage from a sandstone-siltstone-mudstone sequence of the Lower Cretaceous Tugulu Group of Xinjiang comprises the first pterosaur track record from this province and the largest specimen thus far known from China.The pterosaur tracks are assigned to the ichnogenus Pteraichnus based on the triangular overall-shape,the four elongate digit traces and the robust manual digit trace III.Supposed trackmakers were dsungaripterid pterodactyloids whose skeletal remains are well known from the Tugulu Group.The bird tracks that occur on the same surface,are those of typical shorebirds,known from different other localities in southeast Asia.The congruence with Koreanaornis dodsoni described from the same stratigraphic level justifies an assignment to this ichnospecies.This is a further evidence of the co-occurrence of pterosaurs and birds in a typical lakeshore environment with possible seasonal alteration of water supply and aerial exposure indicated by wave ripples,mudcracks and repeated cycles of coarse to fine sediment.Pterosaurs and birds frequented the shoreline and may have fed also on the numerous invertebrates such as the Scoyenia tracemaker that left abundant burrows.HE Qing XING Lida ZHANG Jianping Martin G.LOCKLEY Hendrik KLEIN W.Scott PERSONS IV QI Liqi JIA Chengkai 2013Acta Geologica Sinica(English Edition)2013,87,6:4
8鄱阳湖流域史前人类遗址时空分布及其环境响应(英文)显示文摘The temporal-spatial geographic distribution of archaeological sites and its feature between 10.0–2.8 ka BP(ka BP= thousands of years before 0 BP, where '0 BP' is defined as the year AD 1950) were determined, based on GIS spatial analysis in the Poyang Lake Basin. The relationship between geographic distribution of sites of different periods under subsistence existence of ancient civilizations, climate and environmental change was investigated. The results revealed numerous archaeological sites of the Neolithic Age(10.0–3.6 ka BP). The sites were mainly located in the northern part of the Poyang Lake Basin, a hilly and mountainous area with many river terraces suitable for the development of human civilization. The number of archaeological sites rapidly increased during the Shang and Zhou dynasties(3.6–2.8 ka BP) and spread widely on the floodplains of the middle and lower reaches of Ganjiang River and onto the west, south, and southeast beach areas of the Poyang Lake. Holocene records of climate change suggested that it was possible that climate fluctuations had a great impact on human evolution in the study area. Before 3.6 ka BP, westward and northward expansion of Neolithic cultures in the Poyang Lake watershed occurred under the background of climate amelioration(becoming warmer and wetter). The ancient people lived in the hilly areas with high elevation. The simple mode of a fishing and gathering economy was mostly suited to this area in the early Neolithic Age. The scope of human activities was expanded and cultural diversity developed in the late Neolithic Age. However, with population growth and increasing survival pressure in a dry-cold climatic stage after 3.6 ka BP, this simple living mode had to be abandoned, and various forms of economy, the majority being agriculture, were developed on flood plains of the lower reaches of numerous rivers around Poyang Lake. This promoted flourishing of the Bronze culture of South China.徐佳佳 贾玉连 马春梅 朱诚 吴立 李育远 王鑫浩 2016Journal of Geographical Sciences2016,26,5:3
9晚更新世以来长江三角洲长尺度气候干旱事件——来自沉积物环境磁学的记录显示文摘选择位于长江三角洲南部区域的3个钻孔CSB4、CSB6和CSB8,开展环境磁学方面的研究,以揭示该地区晚更新世以来沉积物记录的显著气候事件。结果显示:3个钻孔都存在明显的S300低值区域,其变化规律为当S300为低值时,磁化率、ARM和SIRM的值较低,而IRMAF80m T/SIRM和ARM/SIRM的比值相对较高,表明磁性矿物浓度降低、粒度变细。同时S300低值区域沉积物以黄色粉砂质黏土为主,含铁锰质结核。IRM获得曲线定量分析结果揭示:沉积物中赤铁矿等高矫顽力组分的含量相对增加,指示长江三角洲区域3次显著的干旱气候事件。在磁性地层及其AMS 14C、光释光测年基础上,推断3次干旱事件发生的时间分别为163―121 ka B.P.(事件I)、57―42 ka B.P.(事件Ⅱ)和14―10 ka B.P.(事件Ⅲ),对应海平面相对较低时期,季风减弱,降水减少,气候干旱,形成以氧化作用为主的环境。周绮娴 杨小强 李剑 林清龙 彭杰 翁元忠 丁洁荧 刘春莲 2016热带地理2016,36,3:2
10Evolution of Neolithic site distribution(9.0–4.0 ka BP) in Anhui,East China显示文摘Based on archaeological surveys of Neolithic cultural development and GIS spatial analysis,this study reproduced the main characteristics of temporal distribution and settlement selection of the sites from the Neolithic Age in Anhui and identified a relationship between environmental evolution and human activity.The results show that altitude,slope direction,and slope gradient were consistent among the settlements at different stages of the Neolithic Age in Anhui,and the sites were mostly distributed in hilly and plain areas on southeast-or south-facing slopes of low gradients close to rivers.We determined that early Neolithic Age(9.0–7.0 ka BP) sites were scattered in small numbers and likely had little cultural exchange with communities of other provinces.The environmental characteristics of various regions in Anhui indicated that the climate was warm and humid with extensive water distribution.The sites of the mid Neolithic Age(7.0–5.0 ka BP) increased rapidly with wide distribution.They were mainly distributed in the plain area north of the Huaihe River and the southwestern areas of Anhui.In the mid Neolithic Age,the warm and humid climate gradually dried,and our ancestors slowly developed cultural exchanges.The largest number of sites existed during the late Neolithic Age(5.0–4.0 ka BP),and were distributed throughout the province.During this period,the overall climate was relatively dry,but humans could still obtain water and other resources through migration.The relatively benign climate facilitated cultural interaction and exchange,which increased during this time,and the Wanjiang culture matured.We also determined that as early civilization evolved,cultures in different regions responded differently to environmental changes.In humid subtropical regions,especially in low-lying plains and areas beside lakes,rivers,and coastal areas,the relatively dry climate in the late period of the middle Holocene,prefaced by a period of high humidity,was conducive to the development of human culture.The evidence from the Neolithic settlements in Anhui therefore reflects this subtropical man-land relationship between cultural development and environmental conditions.WU Li SUN Xiaoling SUN Wei ZHU Cheng ZHU Tongxin LU Shuguang ZHOU Hui GUO Qingchun GUAN Houchun XIE Wei KE Rui LIN Guiping 2020Journal of Geographical Sciences2020,30,9:2
11长江三角洲西部地区13200 cal aB.P.以来环境演变及对长江两岸文化交流与传播影响研究显示文摘长江三角洲西部地区对气候变化反应敏感,但由于缺乏高分辨率的研究材料使学者们对该区域的气候演变过程有着不同的解释,另外,新石器时代环境演变对长江两岸文化交流与传播的影响也还没有引起学者们的关注,为了解决上述科学问题我们在长江三角洲西部高淳地区获得了一个13200 cal a B.P.以来的406 cm厚湖泊沉积剖面,依据孢粉、腐殖化度、烧失量、元素地球化学等古气候记录重建了13200 cal a B.P.以来的气候演变过程并在此基础上探讨了长江两岸新石器时代文化交流与传播路线,研究表明:13200~4400 cal a B.P.期间气候以暖湿为主要特征,但在早期有波动,属于从冷干向暖湿转化的过渡期,4400 cal a B.P.以来以温凉湿润为主要特征,另外,长江三角洲西部地区13200 cal a B.P.以来的气候演变过程并不稳定,高淳剖面古气候代用指标记录了三次气候突变事件,分别为'新仙女木'事件、'8.2 ka'事件和'4.2 ka'事件,6000~4000 cal a B.P.期间的气候变化过程有利于长江三角洲西部长江两岸新石器时代文化之间的交流与传播,沿古中江两岸分布的考古遗址发掘出土的器物表明古中江是长江两岸文化交流与传播的重要通道。姚付龙 朱诚 马春梅 蒋小芳 蔡天赦 2018地层学杂志2018,42,3:2
12Heinrich events recorded in a loess-paleosol sequence from Hexigten,Inner Mongolia显示文摘We describe the last glaciation climatic history Marine Isotope Stage(MIS, 2-4) from 66.7 ka to 14.5 ka in Hexigten, northeast Inner Mongolia, North China. The climate of the region experienced frequent and significant fluctuations between dry-cold and less dry-cold during the late MIS4. The climate was generally warm and humid during early MIS3(MIS3 c) and late MIS3(MIS3 a), whereas it was cold and dry in middle MIS3(MIS3 b) and during MIS2. In this study, the cold and dry conditions were correlated with a stronger East Asian winter monsoon and strong dune activity; whereas, warm and humid conditions were related to a stronger East Asian summer monsoon(EASM) and weak dune activity. This study establishes six distinct dry and cold intervals during the last glacial period(66.7-14.5 ka) based on optically stimulated luminescence data, multi-proxies record(magnetic susceptibility, grain size analysis, Rb/Sr, SiO2/TiO2) and chemical index of alteration(CIA). The last glacial period may be correlated with Heinrich events 1 to 6 which were further confirmed by comparison with the Hulu cave stalagmites and Greenland ice core records. It is concluded that the study area was substantially affected by the EASM, as compared with the loess-desert transition zone of the Chinese Loess Plateau, especially in MIS3 c and suggested that the East Asian monsoon played a pivotal role in the last glacial period climate and dune activity.Ji-Ling Song Hong-Yan Sun Ming-Zhong Tian Xu-Jiao Zhang Xue-Feng Wen Miao Sun 2018Geoscience Frontiers2018,9,2:2
13利用古稻实物遗存揭示中国水稻起源与传播显示文摘古稻实物遗存是探寻水稻起源驯化最直接的实物证据,也是古稻粒形分析的基础。该研究通过对中国现已出土古稻实物遗存及其考古遗址进行归纳总结,并借助前人积累的古稻粒形基础数据,对中国现有不同时空分布的古稻粒形进行整合分析,探寻水稻驯化过程中古稻的粒形变化规律,以揭示中国水稻起源地及其传播方向。结果表明,距今7 000年左右,人类开始有意识地对水稻籽粒形状进行选择,并且粒宽较粒长可能更早引起先民的注意;长江中下游是中国水稻的起源中心,水稻在该地区起源后,逐步向南北两个方向传播,因南北气候条件的差异,促进了水稻的籼粳分化。公婷婷 郑晓明 薛达元 杨庆文 乔卫华 王君瑞 刘莎 梁新霞 张丽芳 程云连 2017浙江农业学报2017,29,1:1
14Challenges at the early stages of the environmental licensing procedure and potential contributions from geomorphology显示文摘Defining impact significance is the main technical task that influences decision-making during the Environmental Licensing Procedure(ELP).The ELP begins with screening to determine potentially significant impacts of the proposed project.Scoping then follows to address any interventions deemed worthy of attention in the production of an Environmental Impact Assessment(EIA).This will include consideration of relevant landforms and geomorphological processes.However,preliminary assessments of environmental impacts often lack the scientific robustness to procure substantive and transactive effectiveness.This review presents an examination of the established practices of screening and scoping while highlighting the foremost challenges to improve the technical grounds of the ELP.The analysis of screening and scoping practices stresses the need for novel methods that ensure the sequential reasoning between their criteria while improving the preliminary evaluation of impact significance.Reducing the inherent subjectivity of discretionary judgment requires scientific methodologies that acknowledge the interaction between the natural system and human interventions,which has been addressed by geomorphological research.The knowledge consolidated in this review opens the gate to explore the compatibility between the United Nations strategy of Ecosystem Approach(EA)with the ELP through a novel geomorphological interpretation of the EIA.Therefore,this diagnosis demonstrate that screening and scoping practices would benefit from reliable methods that balance the precautionary principle with the efficient character required in the ELP.Cristina I.Pereira Celene B.Milanes Rafael Sarda Benjamin Cuker Camilo M.Botero 2021Geoscience Frontiers2021,12,6:0
15Type division and controlling factor analysis of 3rd-order sequences in marine carbonate rocks显示文摘Type division and controlling factor analysis of 3rd-order sequence are of practical significance to tectonic analysis, sedimentary environment identification, and other geological researches. Based on the comprehensive analysis of carbon and oxygen isotope trends, paleobathymetry and spectral-frequency of representative well logs, 3rd-order sequences can be divided into 3 types:(a) global sea level(GSL)sequence mainly controlled by GSL change;(b) tectonic sequence mainly controlled by regional tectonic activity; and(c) composite sequence jointly controlled by GSL change and regional tectonic activity. This study aims to identify the controlling factors of 3rd-order sequences and to illustrate a new method for classification of 3rd-order sequences of the middle Permian strata in the Sichuan Basin, China. The middle Permian strata in the Sichuan Basin consist of 3 basin-contrastive 3rd-order sequences, i.e., PSQ1,PSQ2 and PSQ3. Of these, PSQ1 is a GSL sequence while PSQ2 and PSQ3 are composite sequences. The results suggest that the depositional environment was stable during the deposition of PSQ1, but was activated by tectonic activity during the deposition of the middle Permian Maokou Formation.Yunbo Zhang Zongju Zhao Genhou Wang Zaixing Jiang Mingjian Wang Min Zheng Shiben Zhang 2014Geoscience Frontiers2014,5,2:0
