摘要：对海南岛尖峰岭热带山地雨林森林群落的２０个原始林主要种群和３３个更新林主要种群的生态位特征进行了测定，包括生态位宽度、生态位相似性比例、生态位重叠等。结果表明：组成热带森林的各个种群绝大多数为狭生态位的，种群之间的关系不明确，对资源的分割程度很高，种群之间的生态位相似性比例和生态位重叠指标均很低，反映了热带森林的复杂性。
In this paper,the niche characteristics of main tree populations in tropical mountain rain forest(20 species for original and 33 species for regenerative forest)have been measurted at Jianfengling of Hainan Island.The niche characteristics included niche breadth,niche proportional similarity and niche overlap. The results indicated that:①all of the species in the original forest have the narrow niche,only several species in the regenerative forest have broader niche such as Castanopsis fissa,Sapium discolor,c.tonkinensis etc. according to the Shannon-Wienner′s and Levins′ niche breadth indexes;②the Colwell and Futugma′s proportional similarity index and Levins′ over-lap index values of all pairs species are very low.In the tropical forest,the relationship between populations are very complex and many species share with the resources in a small biotope.
