基于生态系统认识的Logistic土地模型

Understanding of Land Logistic Modeling Based on Ecosystem

在保持生态平衡下合理规划人类用地已经是一个迫切需要解决的问题.从生态系统其他生物种群与人类相互依存的关系建立了两者用地的Logistic模型.由模型的稳定性,着重讨论了参数变化对生态平衡的影响,给出了平衡条件下各参数的关系式,确定了参数取值范围,为人类合理用地提供了依据.

Based on keeping ecological balance and reasonable land planning,it is an urgent and necessary problem for human to use land.This article introduces a Logistic model about the utilization of land between other biological populations and their mutual dependent relationship with human from the viewpoint of ecosystem.On account of the stability of the model,it mainly discusses the model coefficients influencing on ecological balance and also points out the parameter＇s practical significance.What is more,it also offers quantitative reliable assessments for the ecological balance of ecological system,the integrated mode of ecological planning and human＇s utilization of land.
