Analysis on Structure Dynamics of Population of the Secondary Acer mono Forest
Abstract
The static life table of Acer mono populations was compiled based on the population life table and theory of survival analysis using the age class structure represented by the size-class structure.The survival rate curve,the mortality rate curve,vanishing rate curve and survival function curve were determined,and population dynamics were analyzed by spectral analysis.The results show that the number of young individuals was larger than that of middle aged and old individuals.The population had two peak of mortality in size class Ⅲ and Ⅷ.The survival curve of the population appeared to be of the Deevey-Ⅱtype.The population was rise type.The tending management should be actualized to increase the timber utilization quotiety when DBH growth of Acer mono individual reached to 15cm and 40cm in natural conditions.
