本文采用线路、样地与样方调查相结合的方法,结合查阅文献、汇总植物数据库对安徽金寨西河大鲵省级自然保护区开展植物多样性调查。结果表明,保护区植被分为6个植被型组、12个植被型、31个群系;保护区内有蕨类植物27科52属100种,裸子植物5科6属10种,被子植物142科553属1173种,苔藓植物50科95属180种;国家珍稀濒危保护野生植物15种,其中国家重点保护野生植物12种(Ⅰ级2种,Ⅱ级10种),国家珍稀濒危植物9种(2级2种,3级7种)。根据保护区的植物资源现状,从加强保护宣传、加大科学研究和强化执法巡查3个方面提出针对性的保护建议。

This paper combines the survey on route,sample plots and sample areas,conducts a literature review,collects the plant database and further investigates on plant diversity in the Chinese Giant Salamander Provincial Nature Reserve of Jinzhai Xihe in Anhui Province.The result indicates that the vegetation in the reserve can be classified as 6 vegetation type groups,12 vegetation types and 31 formations;in the reserve,there are 100 species,52 genera and 27 families of ferns,10 species,6 genera and 5 families of gymnosperms,1173 species,553 genera and 142 families of angiosperms,180 species,95 genera and 50 families of bryophytes;besides,there are 15 species of national rare and endangered wild plants,including 12 species of wild plants under national key protection(2 species in GradeⅠand 10 species in GradeⅡ)and 9 species of national rare and endangered plants(2 species in Grade 2 and 7 species in Grade 3).According to the current situation of plant resources in the reserve,this paper proposes specific suggestions on protection from the following three aspects:strengthening protection publicity,scientific research and law enforcement and inspection.
