1南昌市生态空间和生态保护红线划定研究显示文摘生态保护红线作为生态空间的刚性约束区域,是保障和维护国家生态安全的底线和生命线。结合国土空间规划双评价技术,以南昌市为例,选取水源涵养功能、水土保持功能、水质保护功能、生物多样性保护功能4种重要性指标和土壤侵蚀、酸沉降、水污染3种敏感性指标,采用模型评估法和净初级生产力定量指标评估法,开展生态空间和生态保护红线划定研究。结果表明:南昌市生态保护红线面积为1648.43 km2,占总面积的22.27%,以水质保护与水污染敏感红线和生物多样性维护功能生态保护红线为主,面积分别为787.93 km2和628.96 km2,主要分布在南昌市梅岭森林公园及周边地区、中部赣江与瑶湖范围、东部军山湖与青岚湖地区、西部鄱阳湖湖域以及近鄱阳湖部分区域,以水域、农田、森林3种地类为主;生态空间面积为4271.43 km2,占总面积的57.70%,主要分布在南昌东部、南部以及西南方向,以农田、森林地类为主;其他空间面积为1482.67 km2,占总面积的20.03%,主要分布在南昌市中部以及市区周边部分地区,以建设用地为主。研究结果可为区域国土空间规划和生态安全提供参考。胡梦姗 叶长盛 卢磊 2021生态环境学报2021,30,3:5
2Sharing earth with all life显示文摘The Anthropocene is marked by twin crises:climate change and loss of biodiversity.Climate change has dominated the headlines,reflecting,in part,the greater complexity that characterizes the biodiversity crisis(Corlett,2020).Since the Convention on Biological Diversity(CBD)was adopted in 1993,the conservation of biological diversity has become a global concern.If we want a sustainable future,we must protect biodiversity.However,biodiversity loss remains one of the most challenges today.Hongwen Huang Hang Sun Zhekun Zhou 2020Plant Diversity2020,42,4:0
3Two new species from Sulawesi and Borneo facilitate phylogeny and taxonomic revision of Engelhardia(Juglandaceae)显示文摘Engelhardia,a genus of Juglandaceae(the walnut family),is endemic to tropical and subtropical Asia.The rich Cenozoic fossil records and distinctive morphological characters of the living plants have been used to explore the evolutionary history and geographic distribution of Juglandaceae.However,the taxonomy of this genus has been suffered from a lack of in-depth investigation and good specimens across its distribution ranges.Species delimitation of Engelhardia was defined with seven species in 2020,but detailed information on the circumscription of the species still remains poorly understood.In this study,two new species are described from Sulawesi and Borneo,Engelhardia anminiana and E.borneensis.We also revised and reconstructed the phylogeny within Engelhardia using morphological,molecular(plastid and ribosomal),and distribution data.We sampled 787 individuals in 80 populations,and all the samples were genotyped using plastid regions,trnS-trnG,rps16,trnL-trnF,psbA-trnH,and rpl32-trnL;one ribosomal region,nuclear ribosomal internal transcribed spacer(nrITS).The all datasets were used to reconstruct the phylogenetic relationships.Then,the molecular analyses were combined for 738 sheets of specimens with 15 morphological characteristics to further explore the morphological clusters of Engelhardia.Cluster analysis using morphological data confirmed the delimitation of nine Engelhardia species.Also,phylogenetic analysis based on molecular data(i.e.,plastid and ribosomal)supported the monophyly of Engelhardia and generated phylogenetic trees that included E.fenzelii,E.roxburghiana,E.borneensis,E.hainanensis,E.anminiana,E.serrata,E.villosa,E.apoensis and the varieties of E.spicata(i.e.,E.spicata var.spicata,E.spicata var.rigida,E.spicata var.aceriflora,and E.spicata var.colebrookeana).Our comprehensive taxonomic revision of Engelhardia will provide an insight into understanding the plant diversity in tropical and subtropical Asia.Hong-Hu Meng Can-Yu Zhang Shook Ling Low Lang Li Jian-Yong Shen Nurainas Yu Zhang Pei-Han Huang Shi-Shun Zhou Yun-Hong Tan Jie Li 2022Plant Diversity2022,44,6:0
