| 摘 要： | 通过对重庆四面山常绿阔叶林群落的NMDS排序，研究了该区植物群落分布与环境之间的相互关系，结果表明：NMDS排序较好地表达了植物群落与环境的变异；四面山常绿阔叶林群落类型及分布主要决于海拔（温度）梯度和土壤水分（湿度）梯度。

| Abstract: | In this paper, the relationship between the plant community distribution and the environment of the evergreen broad leaved forest in Simian Mountain, Chongqing,was investigated with the methods of NMDS ordination. The results suggest that: NMDS ordination expresses the ecological gradients of plant community and environment clearly; The community types of the investigated evergreen broad leaved forest in Simian Mountain, and their corresponding distribution are mainly determined by altitude (thermal) and soil humidity (moisture) gradients. |
