摘　　要：以西藏色季拉山16科、49属、87种珍稀濒危植物为研究对象,通过对其评价指标的定量化和权重分配处理,求得物种的"濒危系数"和"优先保护值",确定了物种濒危等级和优先保护等级。结果表明:(1)西藏色季拉山的87种植物中有1种处于极危状态,13种处于濒危状态,55种处于易危状态,18种处于近危状态。(2)西藏色季拉山有一级保护植物23种,二级保护植物53种,三级保护植物11种。(3)该研究结果与各种保护植物名录的濒危等级和优先保护级别存在较大差异,大部分植物在本区受威胁程度加强,应引起足够重视。16 families,49 genera,87 species of rare and endangered plants in Shegyla Mountains were investigated in this paper.The ＂coefficient of endangerment＂ and the ＂value of superior conservation＂ were obtained through index quantification and weight allocation,thus the endangered levels and conservation priority classes were determined.The result showed that：（1）Of the 87 species studied,there were 1 critically endangered species,13 endangered species,55 vulnerable species,18 near threatened species;（2）23 species belonged to the first class protection,53 to the second,11 to the third.（3）The endangered level and conservation priority classes varied significantly between our research and the lists of endangered plants,most plants were threatened more severely in Shegyla Mountains.
