摘　　要：模拟城市化发展过程方法提取城市化发展中的人口和经济两个主要因子,根据其相互制约的关系,运用非线性理论构筑城市化发展的非线性模型,并采用定性和定量相结合的方法,进行数值模拟,并构建这一模型,解释城市化发展过程中的部分现象。这一模型是理想状态下实现的,无法取得现实中准确的数值,仍需加以修正才能更精确的模拟城市化发展的现实过程。The paper aims to simulate the process of the urbanization development methods.its Based on the mutual restrictive relationship of population and ecomomig which are the two main factors in urbanization development,its and designs the elementary model of urbanization using nonlinear theory and go with the numerical simulation introduces the combinion of both the qualitative and quantitative methods.The model and part of the phenomena in the developing process of urbanization is explained. A conclusion is draun that the model is constructed in the perfect condition,is constructed but the exact data can not be obtained in the practice.So the actual process of a more exact simulation urban development can be realized only after modifying the model.
