广义生态环境演替的改进模型

Improved Model of General Ecoenvironment Evolution

该文从园艺过程、宇宙过程的描述入手,简略地介绍了广义Logistic演替的基本内容,提出了对广义Logistic演替的改进,简述了Ⅰ优化系统的不破不立演替模型、Ⅱ非优化系统的不破不立演替模型、Ⅲ优化系统的不破也立演替模型、Ⅳ非优化系统的不破也立演替模型的基本内容。该文的内容是定性的,目的在于引出一种考虑演化的思路。

From the evolution point of view, the auther improved the eco-environment evolution model-logistic equation, pointed out twokinds of evolution model; Optimum system evolution model and non-optimum system evolution model. We can generalize the biology po-tential(N-d/k)and apply the general Logistic model to environmentresource system, social system, geography system and so on.
