摘要
本文建立了生态系统优势种群序列{X_i}演替模型,并依据N_i-d_i/k_i与N_(i+1)-d_(i+1)/k_(i+1)之间关系的不同情况,分别对种群序列演替模型的4种情况进行了详细的分析。同时对单种群和双种群的一些演替模型进行了系统和详尽的分析,还根据定量分析和计算,提出了划分演替时段区的理论依据。
Jn this paper, a succession model of population sequence {xi} in ecosystem was established. Analyses in detail were made on four cases of the succession model of population sequence under different conditions between Ni-di/ Ki and Ni + 1 - d i + 1/K i + 1.The succession models were investigated systematically with one population and two populations in ecosystem. The theoretical base for the division of three periods was suggested, and some useful results were provided for eco-environmental construction and management.
