摘　　要：在借鉴各种评价模型研究成果基础上,以色季拉山47科102属184种重点野生观赏植物为研究对象,构建了由观赏价值系数、特有性系数、生境系数、蕴藏系数、种内变异系数、濒危系数、抗性系数、可获得性系数等8项指标组成的评价体系,采用K类中心聚类(快速聚类,K-means Cluster Analysis in SPSS)法确定了重点野生观赏植物的优先开发序。By referring the research results of various evaluation models, a priority exploitation ranking system was established for sustainable use of the wild ornamental plants in Mr. Shergyla. It consists of 8 coefficients, which are ornamental coefficient, endemic species coefficient, ecotope coefficient, volume coefficient, variance coefficient, endangered coefficient, resistance coefficient, and gained coefficient. By assigning different weights for them, the value of preferential exploitation （Ve ） was calculated. Then, with K-means Cluster Analysis in SPSS （Statistical Package for the Social Science）, the priority exploitation ranking of the 184 species of wild ornamental plants （ belonging to 107 genera and 47 families） was done. And it will guide protection and utilization wild ornamental plants in Mr. Shergyla.
