安徽黄山北坡常绿阔叶林的生态优势度和物种多样性的研究

A Study on Ecological Dominance and Species Diversity of the Evergreen Broad—Leaved Fofest on the North Slope of Huang Shan Mountain

本文通过对黄山北坡常绿阔叶林群落生态优势度和物种多样性的分析,认为群落中物种丰富度与生态优势度的负相关关系是一条带有普遍性的规律,用它们来反映中亚热带常绿阔叶林的部分生态学特征是适合的。

This paper is about studies on the ecological dominance and species diversity of the evergreen broad—leaved forest of the north slope of the Huangs hanMountain. Ecological dominance and speceis diversity of twelve evergreen broad—leaved plant association are measured. The value of ecological dominance generally vary from 0. 140——3. 680, the value of species diversity generally vary from 1. 159——3. 680, which is negative corrdlated with each other. It is suitable to ehoo—se ecological dominance and diversity as a comprehensive index at community level.
