摘要
在在 broad-leaved/Korean 松( Pinus koraiensis )之间的森林交错群落的优势木种类的比赛和动力学在 Changbai 山的混交林和云杉冷杉木森林(也已知的同样黑暗的针叶树森林)，在东北中国的吉林省被使用 Lotka-Volterra 学习模型，基于从有为每一个的 20 m x90 m 的区域的 28 个样品阴谋的数据。结果证明在自然状况下面，社区的区别跟随了二条指令：一个人将是云杉(Picea jezoensis 和很少 P。koraiensis ) 并且冷杉木(Abiesnephrolepis )co 主导的针叶树森林，并且在平衡，冷杉木绝对是优势的(77.1% 相对优势(RD )) ；其它将是针叶树和阔叶的混交林，并且在平衡，阔叶的树种类是在 broad-leaved/Korean 松混交林的 50% RD 并且 66% RD 在阔叶并且云杉冷杉木混交林。学习证明两 broad-leaved/Korean 松混交林和黑暗针叶树森林是演替顶极群落，交错群落有过渡特征，并且森林社区的多样化建议继任的方向被本地产地影响。
The competition and dynamics of dominant trees species in the forest ecotone between the broad-leaved/Korean pine （Pinus koraiensis） mixed forest and the spruce-fir forest （also known as dark conifer forest） in Changbai Mountain, Jilin Province in Northeast China were studied by using Lotka-Volterra model, based on the data from twenty-eight sample plots with area of 20 mx90 m for each one. Results showed that under natural condition, differentiation of communities followed two directions： one would be Spruce （Picea jezoensis and few P. koraiensis） and fir （Abies nephrolepis） co-dominant conifer forest, and at the equilibrium fir was absolutely preponderant （77.1% of relative dominance （RD））; the other would be the conifer and broad-leaved mixed forest, and at equilibrium, the broad-leaved tree species was 50% of RD in the broad-leaved/Korean pine mixed forest and 66% of RD in the broad-leaved and spruce-fir mixed forest. The study demonstrated that both broad-leaved/Korean pine mixed forest and dark conifer forest were climax community, the ecotone had transitional characteristics, and the diversification of the forest communities suggested that the direction of succession was affected by local habitat.
