POPULATION STRUCTURE DYNAMICS OF PINUS MASSONIANA SECONDARY FOREST IN JILING MOUNTAIN OF HUANGSHAN
摘要
Abstract
Population structure dynamic and Quantitative statistics of Pinus massonianain was determined in Jiling Mountain. Based on the theory of population life table and survival analysis, the life table of Pinus massonianain population was constructed and age classes were replaced with size-classes, thus the population structure dynamic of Pinus massonianain was explored. The results showed that:(1) The population structure of Pinus massonianain in Jiling Mountain was fusiform, characterized by the existences of juveniles and older individuals in small numbers, middle age individuals in a larger part, which to a certain degree reflects a recession form of the species;(2) The mortality of such species increased along with the age and has peaked in the eighth age class; (3) The survival curve of the Pinus massoniana population belonged to the Deevey II type. As a transition population in the subtropic secondary forest, it was a normal phenomenon that the population of Pinus massonianain is substituted. It would benefit to the growth of the other species and to enrich species diversity in this region with appropriate forest tending by humans.关键词
