群落郁閉度不如連續森林大,植物種類也不如連續森林豐富,而且其中夾雜著一些針葉樹。常綠成分種類組成不如連續森林豐富,針葉成分數量上較連續森林的多。Niche breadth of four dominate populations at three age groups was studied by the methods of resource utilization ability and ratio. the result shows that : symplocos sectchuanensis is a typical gengeration species whi ch resource utilization ability is strong, and distribution is wide. meanwhile, go rdonia acuminata, castanopsis fargesis and pinus massoniana specialized at some d egree in resource utilizationm, their distribution is limited. especially, the ju venile of pinus massoniana specialized outstandingly. with the devlopment of pinu s massoniana, which is the pioneer population in mt. jinyun, the environment become s unfit to it ' s juvenile. it turns to needle and evergreen broad - leaves mixed fo r est. because the tolerance toward shading of gordonia acuminata is lower than tha t of castanopsis fargesis, gordonia acuminata will be substituted by castanopsis fargesis and other evergreen broad - leaves species are the edificators. the popul ation ' s ability of resource utilization is the inner factor of population distri bution and community succession. the distribution of light and the concentrate of nutrient ( such as n ) is the outer factors of community succession
