THE COMPARE OF TWO DYNAMIC URBAN MODELS BASED ON SELF-ORGANIZATION THEORY
比较了基于自组织理论的Krugman模型和Allen模型，两者从不同角度模拟城市系统的形成与发展，有助于规划者理解复杂现象。
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.
