• 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
  对缙云山森林植被的4个优势种群3个年龄级生态位宽度进行了研究.结果表明，川灰木利用资源的能力最强、分布广，为典型的泛化种.大头茶、栲树、马尾松对资源的利用在一定程度上特化，分布上有一定的局限性.马尾松的中龄组与幼龄组特化现象十分显著.缙云山森林植被的先锋种马尾松的发展，导致环境的改变不适于其幼龄个体的生长，群落演替到针阔叶混交林阶段，最后发展为以栲树等为建群种的常绿阔叶林.种群的资源利用能力，是种群分布与群落演替的内在原因，光因子和营养元素(如n )是群落演替的主要外部动力
