摘要：Contiguous grid quadrates method was used to set up permanent plot to analyze the population structure and distribution pattern of Cinnamomum rigidissimum in Jianfengling,Hainan Island.The results show that the age structure of C.rigidissimum follow a pyramid form.And it is a steady increasing population with relatively more young trees.For the population distribution pattern,the number of individuals from seedling to big tree reduces step by step.And only few individuals can become big trees.At the stage of big tree,the competitiveness of C.rigidissimum enhances and mortality decreases.The number of survival individuals in the stage of super big tree are larger than those in the stage of big tree.The dynamics of population distribution pattern of C.rigidissimum changes from aggregation to random,when trees grow up gradually.For the young trees,the population distribution follows a clump pattern,which is mainly decided by the biological characteristics of themselves and the environment conditions.For the big trees,the population distribution follows a random pattern,which is mainly decided by interpopulation competition and environmental resources conditions.
