在海南岛吊罗山热带山地雨林设置两５０００ｍ２的样地，分别从物种多样性指数、种－多度曲线、空间格局多样性、时间格局多样性、组成格局多样性对其进行了研究。结果表明海南岛吊罗山山地雨林物种多样性指数Ｓｈａｎｎｏｎ－Ｗｅａｖｅｒ和Ｓｉｍｐｓｏｎ指数分别为４．１９５和０．０２１，均匀度为０．８８０和２．９６２。群落种－多度符合对数级数分布，空间格局多样性表明群落多种群间为随机分布，时间格局的内禀多样性（胸径）表明两样地群落年龄接近，样地２的内禀多样性略大于样地１，这可能是不同地区的环境异质性造成的。组成格局多样性表明群落中种群分散分布，优势种缺乏，生境复杂
Two 5000m2 plots were set up in the tropical mountain rainforest of Diaoluo Mountain, Hainan Island. Species diversity indices, species-abundance curves, spatial pattern diversity, time pattern diversity and composition pattern diversity were studied. The results showed that the Shannon-Weaver and Simpson indices of Shannon-Weaver and Simpson indices of Shanluo mountain rainforest in Diaoluo Mountain, Hainan Island were 4.195 and 0.021, respectively, and the evenness was 0.880 and 2.962. The community species-abundance conforms to the logarithmic series. The diversity of spatial patterns indicates that the populations are randomly distributed among multiple populations. The intrinsic diversity of time pattern (DBH) indicates that the age of two communities is close and the intrinsic diversity Slightly larger than sample 1, which may be caused by environmental heterogeneity in different regions. The pattern of diversity indicates that the population disperses in the community, the dominant species are lacking and the habitats are complex
