摘　　要： 应用方差分析、χ２检验、相关系数的ｔ检验和双变量复合个体－距离法对海南岛热带山地雨林种间联结进行了分析，结果表明物种间大部分为独立分布，少部分为正联结，负联结很少，说明种群个体旁更易为其它种群个体占领，在一定程度上表明动物在维持热带雨林多样性方面有一定作用．同时以上方法中双变量复合个体－距离法较好． A series of techniques,including the analysis of variance、 χ 2 test based on a 2×2 contingency table、 t test of correlation coefficients and bivariate combined count distance analysis,are used to determined the interspecific association in montane rain forest in Diaoluo mountain,Hainan.The results show that most of the species have no association,some of them have positive association,and few are negative association.These show that the space around one species can be easilier occupied by other species,and nature enemies may play a role in maitaining speices diversity in tropical rain forest.Among four methods used above,the bivariate combined countdistance analysis is found the best.
