摘要
据根对缙云山森林群落中优势种生长量的多元线性回归分析,发现有的种间线性相关显著,有的不显著.对线性相关显著的优势种,进一步应用Lotka-Volterra竞争模型进行了预测,预测结果同其它方法预测结果及实地调查结果基本一致.分析说明了在这些线性相关显著的种间,种间竞争是演替的主要动力;而那些线性相关不显著的种间,其它因子才是演替的主要动力.
The rclatioship of growth among dominant species in Jinyn Mountain of Sichuan Province is studied in this paper. That is to say that there is competition among these dominant species. The Lotka-Volterra competition model is used to predict the succession of community. The result is similar with the Markovian model. This illustrates that the competition among this species is the main factor of succession. Among these species with nonlinear relation in gro wth, the competition is not the main factor to influence succession process. This paper is only a preliminary discussion, for some communities, changes are observed over time but the causes are not known. This problem is particularly critical in communities influenced by human disturbance.
