摘　　要： 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。 The biodiversity of mountain rain forest in Diaoluo Mountain was studied by using diversity indices,species abundance relation,spatial pattern diversity,temporal pattern diversity and compositional pattern diversity. The Shannon Weaver and Simpson indexes is 4 195 and 0 021 respectively,the evenness is 0 880 and 2 962.The species abundance relationship fits logarithmic series distribution.The distribution of species is random form of the spatial pattern diversity,and intrinsic diversities (diameter class) of two plots are similar from temporal pattern diversity.The compositional pattern diversity shows the complexity of community:dominant species is rare and most species are randomly distributed.From the spatial pattern diversity and relationship between it and the nearest neighbour,we conclude that Janzen Connell hypothsis is possibly true in the tropical rain forest.
