  3. 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

    對縉雲山森林植被的4個優勢種群3個年齡級生態位寬度進行了研究.結果表明,川灰木利用資源的能力最強、分佈廣,為典型的泛化種.大頭茶、栲樹、馬尾松對資源的利用在一定程度上特化,分佈上有一定的局限性.馬尾松的中齡組與幼齡組特化現象十分顯著.縉雲山森林植被的先鋒種馬尾松的發展,導致環境的改變不適于其幼齡個體的生長,群落演替到針闊葉混交林階段,最後發展為以栲樹等為建群種的常綠闊葉林.種群的資源利用能力,是種群分佈與群落演替的內在原因,光因子和營養元素(如n )是群落演替的主要外部動力
