| 摘 要： | 马尾松林是三峡库区主要植被组成之一。实地调查表明： 目前三峡库区马尾松林可分为２１ 个群落类型；群落成层现象明显，可分为乔木层、灌木层和草本层；物种丰富度、多样性、均匀度在群落梯度上的分布规律均为：草本层＞ 灌木层＞ 乔木层；在海拔梯度上的分布无规律性。

| Abstract: | Pinus massoniana forest is a major component of the vegetation in the Sanxia Area. Field investigations revealed that the forests in the area could be sorted into 21 types of community, with obvious community layers, such as arbor layer, shrubs layer and herbaceous layer: and the richness, diversity and evenness of species in distribution showed such a regularity as herbaceous layer > shrubs layer > arbor layer and no regularity along the altitude. |
