摘　　要：传统的经济地理学模型由于在时间上是静止的 ,并且忽略了空间各主体间的相互作用机制 ,因而是在均衡的状态下对交通、土地使用和环境系统进行描述。从而在指导规划实践过程中往往存在着一些问题。随着复杂科学的进展与其对经济地理学的渗透 ,一些新的理论运用复杂科学的成果成功地对传统的经济地理学模型进行了改造。本文正是介绍并比较了这样的两种城市结构自组织模型 :Krugman的自组织模型与Allen的自组织模型。这两种模型都是基于自组织理论 ,但又从各自不同的角度出发 ,模拟了城市系统的形成与发展 ,有助于规划者理解他们所必须面对的复杂现象 。Because it is static on timing, and neglected the spatial interaction mechanism of different agents, the traditional economic geography model describe traffic, land use and environment systems in equilibrium conditions. For this reason there are some problems during planners use these models to direct urban and regional planning. As the developing of complex science, some new theories utilize the productions of complex science to reconstruct the traditional economic geography models. In this paper, we introduce and compare two of these models: Krugman's model and Allen's model. These two models are both based on self-organization theory. But they simulate the form and development of urban systems from different points of view. These models will be beneficial to planners comprehend the complex phenomena that they have to faced to, so the models have great theory and practical values.
