摘要
通过野外调查、标本鉴定、文献整理,编制了呼伦贝尔市国家级重点保护野生植物名录,并分析了其区系地理成分、县域空间分布及濒危状况。结果表明:呼伦贝尔市共有国家重点保护野生植物19种,隶属于12科15属,包括真菌类2种、苔藓类1种、被子植物14种;区系地理成分以泛北极、东亚分和古北极为主。在县域分布上,鄂伦春自治旗最多(13种),其次为牙克石市(12种)、扎兰屯市(11种)、阿荣旗(11种)、额尔古纳市(11种),其余旗、市分布的国家重点保护野生植物均小于10种。按照IUCN评估,濒危植物(EN)4种、易危植物(VU)9种、近危植物(NT)4种、无危植物(LC)2种。呼伦贝尔市大部分国家重点保护野生植物主要分布在大兴安岭区域,均受到不同级别自然保护区的保护。本研究结果可为区域植物多样性研究提供科学依据。
Through field investigation,specimen identification and documentation,a list of wild plants under national key protection in Hulunbeier was compiled.We analysed their zonal geographic composition,county spatial distribution and endangered status.The results show that there are 19 species of wild plants under national key protection in Hulunbeier,belonging to 12 families and 15 genera,including 2 species of fungi,1 species of bryophytes and 14 species of angiosperms.The geographic composition of the zone is dominated by Holarctic element,East Asia element and Palaearctic element.In terms of county distribution,,Oroqen Autonomous Banner has the most species(13 species),followed by Yakeshi City(12 species),Zalantun City(11 species),Arun Banner(11 species),Ergun City(11 species),and the rest of the banners and municipalities have less than 10 species of wild plants under national key protection.According to the IUCN assessment,there are 4 species of endangered plants(EN),9 species of vulnerable plants(VU),4 species of near-threatened plants(NT)and 2 species of non-threatened plants(LC).Most of the state key protected wild plants in Hulunbeier are mainly distributed in the Great Xing′an mountains region,and are protected by nature reserves at different levels.The results of this study can provide a scientific basis for the study of regional plant diversity.der to provide scientific basis for the ecological quality evaluation and ecological environment protection policy formulation of similar regions in the Xinjiang Production and Construction Corps.
