海南尖峰岭热带雨林方枝蒲桃的种群结构特征与动态分布
Characteristics of Population Structure and Growth Status of Syzygium tephrodes in Jianfengling Tropical Rainforest,Hainan,China
摘要
Abstract
In this study,we took Syzygium tephrodes as the object in a 60 hm2 large sample plot in Jianfengling,Hainan,and investigated the structural characteristics and growth dynamics of its population,as well as the intensity of inter-plant competition and its distribution pattern.The results showed that:(1)S.tephrodes populations have strong natural renewal ability,abundant seedlings,and the mortality rate of the populations increased or decreased with the increase of the diameter level and then decreased rapidly at the Ⅳ stage,and the fluctuation amplitude was the most obvious at the Ⅳ-Ⅴ diameter level,and the mortality rate declined rapidly after the Ⅳ level and tended to be stabilized.(2)The survival curves of S.tephrodes were of Deevey-Ⅲ type,the mortality rate was high in the early stage,and low once it reached a certain age.(3)The results of the time series prediction showed that the number of individuals in each age class increased to different degrees after the next 2,4 and 6 age classes.In conclusion,the mortality rate of young individuals in S.tephrodes population was high,but there was still a certain potential for renewal.This study provided theoretical support for the landscaping application and protection strategy formulation of S.tephrodes.It was recommended to further strengthen habitat protection and take appropriate intervention measures to promote stable population development within the community.关键词
