Examples
- Study on the spatial distribution patterns of symplocos setchuanensis population in different communities in the jinyun mountains
四川山矾种群在不同群落中空间分布格局研究 - 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
所有这些果实和种子的化石在中国均为首次报道，其中蜡瓣花属、鹅掌楸属、蓝果树属、清风藤属和山矾属还是该属在中国的首次大化石记录。 - There were 66 species in the community 3 ( castanopsis fargesii + schima superba - itea chinensis - maesa japonica community ) , and castanopsis fargesii and schima superba were the dominant species of tree layer , and itea chinensis and symplocos sumuntia were the dominant species of succession layer , and maesa japonica and ardisia japonica was the dominant species of regeneration layer
采用物种数、 m雌alef丰富度指数、 simpson和shannon一wiener多样性指数、 simpson和shannon一wiener均匀度指数对黄茵岭生态保护小区森林群落多样性进行测定，结果表明该地区有较高的物种多样性。 - 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
用物种重要值代替物种多度来测定物种多样性，结果表明: margalef丰富度指数随着群落层次的物种数增加而增加，与群落各层次的个体数无关，各群落的乔木层的simpson多样性、 shannon一wiener多样性、 simpson均匀度、 shannon一wiener均匀度4个指数一般小于其演替层的相应指数，演替层与更新层的相应指数之间无必然大小关系。 - 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
