【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.更多还原
