杭州西湖风景名胜区陆生维管植物物种多样性现状与分析

Current Situation and Analysis of Terrestrial Vascular Plant Diversity in Hangzhou West Lake Scenic Area

摘要: 2020年至2022年对杭州西湖风景名胜区内的陆生维管植物进行了调查。通过对历史文献的收集和对本次调查结果的评析，共记录陆生维管植物1223种（含种下单位），隶属156科，610属。记录区域内新增野生或逸生植物15种，并对65种植物在区域内的现存提出质疑；同时对物种的科属组成、生活型组成、珍稀濒危植物现状及外来植物进行了分析；本次调查到珍稀植物14种，记录具潜在风险的外来植物34种，其中新增7种；最后对景区的植物多样性保护提出了合理建议。

Abstract: During July and December of 2020, and from February to July 2021, field survey was carried out on terrestrial vascular plant in Hangzhou West Lake Scenic Area, Zhejiang province by line transect. The result demonstrated that there were 1223 species (including taxa below species level) belonging to 156 families and 610 genera. 15 wild or alien species were added. Analysis was made on the composition of the family and genus of the species. Plant life form, current situation of rare plants, and the alien plants were also analyzed. 14 rare plants, 34 alien plants with potential risks were recorded, of which 7 species were added.
