| 摘 要： | 本文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，并应用植物群落的排序值与环境因子的多元回归分析给出了植物群落类型与生态梯度的定量环境解释。结果表明：ＮＭＤＳ排序较好地反映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取决于海拔高度和土壤含水量，并可通过与环境参数的回归模型定量地确定。

| Abstract: | In this paper, the relationship between the plant community distribution and the environment of evergreen broad - leaved forest in Simian M. Chongqing, was investigated with the methods of NMDS ordination. And the quantitative environmental interpretation of plant community type and ecological gradients is given by the multivariate regression analysis. 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 M. and their corresponding distribution are mainly determined by altitude (thermal)and soil humidity (moisture) gradients. They are quantitatively determined by regression models which contains environmental parameters. |
