摘要：应用植物群落学的理论和方法,对西藏色季拉山西坡种子植物花卉资源进行调查研究,结果表明：色季拉山西坡有花卉植物52科,133属,219种;菊科和蔷薇科等是这一区域优势科,杜鹃属和忍冬属等是这一区域优势属;急尖长苞冷杉和杯萼忍冬分别是木本乔木类花卉和木本灌木类花卉中资源最优势且分布范围最广的花卉种,草本攀援类花卉呈现出资源相对优势的种分布较狭窄而分布广的种资源量较小的趋势;从垂直高度上看,海拔3 500 m附近的花卉平均物种数最多,海拔4 200~4 800 m带的物种多样性最高;花卉物种中有20种中国物种红色名录收录种,其中有2种国家Ⅱ级保护植物。
Applying the theories and methods of phytosociology,the authors investigated and studied seed plants flower resources in western slope of Sejila Mountain,Tibet,China.The results show that the western slope of Sejila Mountain has 52 families,133 genera and 219 species of flower plants;The Compositae is the most dominant family and the Rhododendron is the most dominant genus in this region;Among all the tree flower species,Abies georgei is the most resources and the most widely distributed species;Among all the shrub flowers,the species with the highest important value and the most wide distribution is Lonicera inconspicua.The herb and climbing flower show a trend that the species owed higher important value has a narrow distribution and the species with a wide distribution has a lower important value;From the point of vertical height,that with the most average number of species of flower plant is 3 500 m and with the highest diversity of species is 4 200～4 800 m;Of all the flower species 20 species are included in China Species Red List and two species are Chinese protected plantsⅡ.The authors also proposed some management recommendations according to the status quo of the flower resources.
