复杂科学与城市规划变革

从分析当代城市规划学的困惑的表象和原因入手,进而提出城市作为复杂自适应系统的基本特征。并据此归纳出城市规划学变革的方法论——新理性主义的四方面特征:从单一连续性转向连续性与非连续性并存;从注重确定性转向确定性与非确定性并存;从突出城市的可分性转向可分性与不可分性并存;从严格的可预见性转向可预见性与不可预见性并存。进而从这四方面"并存"提出基于复杂自适应系统规律的城市规划变革七方面重点,即:对城市总体规划进行期中评价;推行低冲击开发模式;强调层层嵌套式的城市结构;倡导用地混合与交往空间;实施从下而上的"社区魅力再造";提倡弹性的规划结构;形成城市群的协同机制。

COMPLICATED SCIENCE AND URBAN PLANNING REFORM

By analyzing the puzzling phenomena and their causes in the modern urban planning science, this paper presents the basic characteristics of the city as a Complex Adaptive System (CAS). Then it induces the methodology of urban planning reform which has four features of neo-rationalism: from continuity to the coexistence of continuity and discontinuity, from certainty to the coexistence of certainty and uncertainty, from dividability to the coexistence of dividability and undividability, from predictability t...
