摘　　要：利用不同林龄的华山松人工林的群落结构、物种组成等调查数据,采用群落构成指数等因子构建评价模型,对昆明市华山松人工林的生态系统健康状况进行评价.通过分析评价得出结论:华山松人工林的健康指数随着林龄的增长而增长,但是51 a华山松林的健康指数仍远小于天然次生林.By taking the surveying data of community structure and species composition traits of the Pinus armandii plantation,and using the CI（Compositional Index）,we developed an evaluation model to assess the health condition of the Pinus armandii plantation in different age.The results showed that the health index was increasing with the forest age growth,but the health index of 51a Pinus armandii plantation was far less than natural secondary forest.
