摘要(Abstract):

川西共有保护植物87种,隶属于55科69属,在经向、纬向以及海拔分布上都具有明显的规律,大致北纬27°~30°25′,东经100°~103°52′,海拔1 500 m~2 500 m的区间保护植物种类最丰富;为把有限的人力和财力投入到重要的保护物种上,根据川西保护植物自身特点,本文采用定量评价的指标和方法,因地制宜地确定川西保护植物:一级为43种,二级为40种,三级为4种。
There are 87 species of protection plants belonging to 55 families and 69 genera in Western Sichuan province,and their distributions have obvious laws in the 3 directions of longitude and latitude and altitude.And approximately between N27°~30°25′,E100°~103°52′,1 500 m~2 500 m a.s.l.,there are the richest species of protection plants.In order to make these limited manpower and wealth use for important protected species,this paper uses criterions and ways of quantitative estimate to ascertain protection plants in Western Sichuan.The results have indicated that the first grade has 43 species,the second grade has 40 species,and the third grade has 4 species.
