摘 要 ：本文探索森林群落组成结构水平的定量描述方法。通过用Shannon—Wiener多样性指数、Simpson生态优势度指标以及群落均匀度指标，测定广东范围内22个森林群落的物种多样性、生态优势度和群落均匀度。结果表明这三种指标值能有效地表征群落的组成结构特征；广东亚热带常绿阔叶林群落的物种多样性指数为4—5左右，群落均匀度为0.7—0.8左右，生态优势度为0.08—0.12左右。文章还对测定结果进行分析，进一步探讨了三种指标值的相互关系，三种指标值在群落学研究中的意义，以及在林业实践上的作用等。

Abstract:The paper studies on the characters of organization of forest communities in Guangdong. The diversity and ecological dominance as well as community evenness of twenty two forest communities in Guangdong are measured on the basis of Shannon-Wiener index and Simpson index as well as evenness formula. The results show that three indexes have an effect on explaining the organization level of forest community. The species diversity index of subtropical evergreen broadleaved forest is about 4—5, the ecological dominance is about 0.08—0.12, the community evenness is about 0.7—0.8. According to the further research of the measured results, the relationships between three indexes and the meaning of three indexes in community study as well as the application of three indexes in foresty practice are discussed
