城市老中心区空间形态影响因素的评价理论及方法研究

Research on evaluation theory and method of factors influencing spatial form in old urban central area

文章在分析影响城市老中心区空间形态主要因素的基础上,建立了相对应的一级评价指标和二级评价指标,综合模糊评价方法对城市老中心区建筑模型、公共空间模型和交通模型3个方面进行权重确定,并将权重与城市区域网络的变化建立函数关系,在函数图像中与各个一级指标的最佳舒适值进行对比,进而确定在某个合适的区域面积内城市空间形态的最佳状态。最后,文章以杭州市上城区老中心区为典型案例验证了该文提出评价方法的科学性,为城市规划和管理提供了决策依据。

Based on the analysis of the main factors influencing the spatial form in old urban central area,the corresponding first-level evaluation index and second-level evaluation index are established,and the weight determination of the building model,public space model and traffic model in old urban central area is conducted by using comprehensive fuzzy evaluation method.The function relation between the weight and the changes of area mesh is established,and the actual value is compared with the best comfort value of each first-level index in the function graph,and then the best spatial form in a certain area of the city can be found out.Finally,taking the Shangcheng District in Hangzhou City as an example,the scientificity of the proposed evaluation method is validated,hoping to provide a basis for making decisions about urban planning and management.
