摘　　要：为了了解霸王岭地区以壳斗科植物为优势的山地雨林群落的主要种群的空间分布格局,以及格局的动态变化规律,更好、更全面地管理和保护山地雨林,通过对样地群落中8个主要的乔木种群,采用样方法取样和方差均值比的方法进行检验分析。结果表明,红锥、红椆、肉实树3个种群为随机分布类型,公孙锥、鸭脚木、岭罗麦、黄杞和狭叶泡花5个种群为集群分布类型。反映出群落正处于演替的中期阶段,随着演替的发展,随机分布类型会逐渐上升。各种群的分布格局动态变化过程可分为5种类型:Ⅰ型:红锥、公孙锥和狭叶泡花种群的集群—随机—随机模式;Ⅱ型:鸭脚木种群的集群—集群—随机模式;Ⅲ型:黄杞种群的随机—集群—集群模式;Ⅳ型:肉实树和红椆种群的随机—随机—随机模式;Ⅴ型:岭罗麦为随机—集群—随机,表现出不同种群的生长、发育模式有较大的差异性。In order to understand the spacial distribution pattern and the dynamic changes of spacial distribution pattern of the major tree species in the Fagaceae dominance in tropical montane rain forest in Hainan island,people will better and roundly manage and protect the montane rain forest.In this plot,there were 8 major tree species.By method of variance/mean,the author found that Castanopsis hystrix,L.fenzelianus A.Camus and Sarcosperma laurinum were random distribution pattern and Castanopsis tonkinensis,Schefflera octophylla,Tarennoidea wallichii,Engelhardia roxburghiana and Meliosma angustifolia were cluster distribution pattern.By study on change of speices distrbution pattern,the author found that there were 5 change types of different grade species.Castanopsis hystrix,Castanopsis tonkinensis and Meliosma angustifolia belonged to the typeⅠ of Cluster-Random-Random;Schefflera octophylla belonged to the type Ⅱ of Cluster-Cluster-Random;Engelhardia roxburghiana belonged to the type Ⅲ of Random-Cluster-Cluster;Sarcosperma laurinum and L.fenzelianus A.Camus belonged to the type Ⅳ of Random-Random-Random;Tarennoidea wallichii belonged to the type Ⅴ of Random-Cluster-Random by the analysis of changes of these species distrbution patterns.These results showed that the different population had more differences in growth and development.
