摘　　要：在野外调查和查阅文献资料的基础上,研究了七姊妹山自然保护区国家重点保护野生植物的分布情况,并运用濒危系数、遗传价值系数和物种价值系数对其优先保护顺序进行了定量分析.结果表明:(1)七姊妹山自然保护区共有国家重点保护野生植物28种,其中Ⅰ级7种,Ⅱ级21种,分别占湖北省分布的60.9%、87.5%和55.30%;(2)采用优先保护评价体系对28种国家重点保护植物进行排序,其结果与《国家重点保护野生植物名录(第一批)》结果有所不同,属一级保护的有银杏和伯乐树2种,占总数的7.14%;属二级保护的有桢楠、连香树、光叶珙桐、红豆杉、珙桐、黄杉、花榈木、篦子三尖杉、毛红椿、巴山榧树、水青树、红豆树、闽楠、南方红豆杉、莼菜、红椿和川黄檗17种,占总数的60.71%;属三级保护的有喜树、香果树、鹅掌楸、榉树、厚朴和凹叶厚朴6种,占总数的21.43%;属四级保护的有金荞麦、樟树和野大豆3种,占总数的10.71%;(3)该评价体系对28种植物的评价与分级结果更真实地反映了它们在该区域受威胁状态和优先保护顺序,对该区野生重点保护植物的优先保护工作具有一定指导意义.Based on the field investigation and known data, the distribution of the national key protected wild plants in Qizimeishan Mountain Nature Preserve was studied and analyzed in this paper,and the priority conservation of the national key protected wild plants was quantitative analyzed by using the threatened coefficient, the genetic coefficient and the species value coefficient. The results showed that （1） there were 28 species of the national key protected wild plants in Qizimeishan Mountain Nature Preserve,among which 7 species belonged to the first class,2l belonged to the second class,and each accounted for 60. 9%-87. 5%and 55.3 % of the Hubei province＇s distribution, respectively; （2）28 species of the national key protected wild plants were sequenced by the system of priority conservation and evaluation,and the results were different from《 the checklist of national key protected wild plants （the first passel）》. Ginkgo biloba and Bretschneidera sinensis belonged to the first rank preserve, and accounted for 7.14 Yo Phoebe zhennan ,Cercidiphyllum japonicum , Davidia involucrata var. vilmoriniana, Taa：us chinensis, Davidia involucrata , Pseudotsuga sinensis , Ormosia henryi , Cephalotaxcus oliveri , Toona ciliata var. pubescens, Torreya fargesii , Tetracentron sinense , Ormosia hosiei , Phoebe bournei , Taxus chinensis var. mairei, Brasenia schreberi , Toona ciliata and Phellodendron chinense belonged to the second rank preserve, and accounted for 60. 71% ; Camptotheca acuminata , Emmenopterys henryi , Liriodendron chinense , Zelkova schneideriana , Magnolia officinalis and Magnolia officinalis ssp. biloba belonged to the third rank preserve,and accounted for 21.43% Fagopyrum dibotrys,Cinnamomurn camphora and Glycine soja belonged to the fourth rank preserve,and accounted for 10.71%;（3） Plant threatened status and priority preservation sequence were more truly reflected by the evaluation and rating results from this evaluation system. Therefore it is very significant for the priority con
