三峡库区珍稀濒危植物

Study of the Rare and Threatened Plants in the Three Gorges Reservoir Area ~

三峡库区共有高等陆生植物6088种，珍稀濒危植物56种，其中Ⅰ级保护物种4种，Ⅱ级保护物种23种，Ⅲ级保护物种29种，处于濒危状态的7种，渐危状态的27种，稀有状态的22种。在分析三峡库区珍稀濒危植物种类组成、地理成分、现状分布的基础上，探讨了库区珍稀濒危植物致危原因及目前所采取的保护措施中所存在的问题，并提出了相应的保护对策。

There are 6 088 high plant species in the Three Gorges Reservoir Area, of which 56 species are rare and endangered species, 4 species belong to the first class of nation protection plants, 23 species belong to the second class of nation protection plants and 29 species belong to the third class of nation protection plants. According to their current status, 7 species are endangeredspecies, 27 species are vulnerablespecies and 22 species are rarespecies. Based on the analysis of the species composition, areal-types of their generaand distribution, the reasons that caused the species endangered and the problems of the current measures taken for the species conservation were discussed. The conservation strategies for the species were proposed.
