栲 的英文怎麼說

Previous researchers have always determined the sp atial distribution patterns ( sdp ) of castanopsis kawakamii with a sample - dis tance method. however, the distribution patterns may be affected by the quadrat si ze and, in the course of analysis, the density differences among the cluster plots are not considered ; therefore, differences of cluster plot size and the dispersi on degree among individuals of cluster plots can not be known. authers of this pa per have determined the spatial distribution patterns of castanopsis kawakamii population in different habitats by means of non - quadrat distance method and a nalysed the pattern intensity and grain of the sdp. the pattern intensity is defi ned with the relative density differences and the pattern grain can embody the d ispersion degree of the individuals in the plots, and the dispersion degree among the plots. the determined results are as follows. the intensities of the species range in order from strong to week : litsea mollifolia p. kawakamii i. purpure a r. cochinchinensis c. kawakamii c. carlessii d. oldphamii s. superba. the gra ins of the species queue in order from coarse to close : s. superba = litsea mollif olia r. cohinchinensis c. kawakamii = i. purpurea c. carlessii p. racemosam d. oldp hamii. these determined results tally basiclly with the results authers of this paper have got in determining the same plots by means of aggregate index access ing method. in view of this, it is held that the sdp of c. kawakamii is closely related to the habitats and biological features

前人都是採用樣方方法對格氏栲種群數量的空間格局進行測定，而格局分佈有可能受樣方大小的影響，且分析過程中沒有涉及聚塊間密度差的問題，因而無法掌握種群的聚塊大小差別及聚塊內個體間的離散程度.本研究採用無樣方距離法，測定不同生境的格氏栲種群空間格局，分析格氏栲種群格局的強度和紋理.強度以聚塊和間隙的密度差來定義，紋理則是體現聚塊內個體間的離散程度與諸聚塊間的分離程度.測定結果表明，格氏栲種群格局強度從高到低排列次序為：木姜子蚊母樹冬青茜草樹格氏栲米櫧虎皮楠木荷；格局紋理從粗到細的順序是：木荷=木姜子茜草樹格氏栲=冬青米櫧蚊母樹虎皮楠.這一測定結果與作者採用聚集度指標測定相同樣地格氏栲種群空間格局的結果基本相符.因此，格氏栲空間格局類型及分佈與格氏栲生物學特性及生境的關系密切

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

The study shows that the early and late seed rains of constructive tree species in evergreen broadleaved forest at chongqing simian mountain had no activity. the bigger the seeds of the species and the earlier or later the seeds of the species matured, the higher the proportion of the seed rain damaged by animals. the quantitative variation of seed rain, active seed rain and seed bank did not take place at the same time. at early time, the number of seed banks of castanopsis fargesii, lithocarpus glabra, quercus myrsinrefolia, castanopsis plasyacantha, cinamomum subavenium. which own more active seed rain increased by geomitric series. the seed banks of castanopsis orthacantha and schima argentea were small, only survived a short time, and did not sprout next year. the quantitative dynamics of seed banks and their increasing or decreasing rates were decided by the proportion damaged by animals, dying speed of seeds and their resistance to pathogens and adverse circumstances, and the state of seed germination
