本文对常绿阔叶林的区系组成、生活型谱、叶的性质以及群落结构等进行了研究。结果表明：组成植被的热带属略占优势，区系组成极为分散，常绿建群种大多在Ｃａｓｔａｎｏｐｓｉｓ、Ｃｙｃｌｏｂａｌａｎｏｐｓｉｓ二个属中；植被性质主要表现为中亚热带常绿阔叶林特征，并逐渐向北亚热带过渡。优势种群的结构表明，本区植被已接近常绿阔叶林演替的顶极阶段。 In this paper, the fauna composition, life form spectrum, leaf properties and community structure of evergreen broad-leaved forest were studied. The results showed that the tropic genera of vegetation belonged slightly dominant and the flora composition was extremely dispersed. Most of the evergreen constructive species were found in two genera of Castanopsis and Cyclobalanopsis. The vegetation characteristics were mainly characterized by the subtropical evergreen broad-leaved forest, North subtropical transition. The structure of dominant populations shows that the vegetation in this area has approached the climax of the succession of evergreen broad-leaved forests.
