BIODIVERSITY OF THE MONTANE RAIN FOREST IN DIAOLUO MOUNTAIN,HAINAN
海南岛吊罗山山地雨林物种多样性

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.
