本文从拓扑学的观点上去整体地描述森林群落演替的动态平衡理论,试图从原理上证实群落演替的顶极学说的合理性,给出了拓扑学的两个不变性一连通性和Brouwer不动点定理在森林生态学上的应用。 依照生态学家的观点,植物群落是对应于个体生态学的而从系统的角度去考虑的整体生物学的一个重要研究对象。植物群落不但“本身是涉及众多有机体的巨大复合体,”而是由“通常是大量的、较为连续的,以及在一年之中表现有规律的种类 This paper describes the dynamic balance theory of forest community succession from the perspective of topology and attempts to prove the rationality of the top pole theory of community succession theoretically. It gives two invariance-connectivity and Brouwer Application of Fixed Point Theorem in Forest Ecology. According to ecologists, plant communities are an important research object of holistic biology that is systematically considered in response to individual ecology. Not only is the plant community “itself a huge complex involving many organisms,” but "usually large, relatively continuous, and behaving regularly throughout the year
