山礬科
  1. 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
  2. All these fossil fruits and seeds are reported for the first time in china, and corylopsis, liriodendron, nyssa, sabia and symplocos are new additions to the chinese megafossil plants

  3. There were 83 species in the community 4 ( castanopsis sclerophylla - camellia oleifera - maesa japonica community ), and castanopsis sclerophylla, castanopsis fargesii and schima superba were the dominant species of tree layer, and camellia oleifera, itea chinensis and symplocos sumuntia were the dominant species of succession layer, and maesa japonica was the absolute dominant species of regeneration layer. there were 76 species in the community 5 ( castano

    用物種重要值代替物種多度來測定物種多樣性，結果表明: margalef豐富度指數隨著群落層次的物種數增加而增加，與群落各層次的個體數無關，各群落的喬木層的simpson多樣性、 shannon一wiener多樣性、 simpson均勻度、 shannon一wiener均勻度4個指數一般小於其演替層的相應指數，演替層與更新層的相應指數之間無必然大小關系。
