Abstract:In this paper , the population characteristics of ornamental plant Daphniphyllum macropodum Miq.in evergreen and deciduous broad-leaved mixed forest in Xingdoushan Nature Reserve were studied . The results showed that: the population age structure of Daphniphyllum macropodum Miq.is pyramid-shaped ,a typical type of population growth;its population of individuals are mainly distributed in vertical space of the community under 9 m;on the elevation gradient ,because of the reasons of the development degree of community and habitat conditions ,in the 1 400~1 500 m range gradient,the largest number of individuals of the population distribution;the population distribution patterns is cluster;the life table anal-ysis showed that , in the first grade DBH 1 diameter seedlings in the community , the Daphniphyllum macropodum Miq.located lowest and the advantage of other individuals in a population seedling competi -tion for resources and space is not obvious , viability is weak , life expectancy is not high , the population survival curve for ″Ⅱtype″,the survival rate in each life story stage are roughly equal .
