京杭大运河沿线主要城市空间形态的综合测度研究

The comprehensive measurement of spatial forms of major cities along the Beijing-Hangzhou Grand Canal

京杭大运河作为连接中国南北地区之间的经济、文化发展与交流的走廊,历来对促进沿河城市兴起与繁荣发挥着关键作用。研究选取京杭大运河沿线8个主要城市的空间形态进行对比研究,利用空间句法对城市空间网络进行解构,并分析各个城市内部结构的不同之处;运用城市分形维数和紧凑度指数对不同城市进行计算,对城市空间外部形态特征进行分析;并将这些城市分为城市空间形态简单、城市空间形态较复杂和城市空间形态复杂三大类。最后根据分析结果提出针对性的城市发展建议,以期为大运河沿线城市以及此类其他沿河城市的空间形态发展提供参考。

The Beijing-Hangzhou Grand Canal,as a corridor connecting economic and cultural development and exchange between the north and south regions of China,has been playing a crucial role in promoting the rise and prosperity of cities along the river.We selected eight major cities along the Beijing-Hangzhou Grand Canal for the comparative study on their spatial forms,used spatial syntax to deconstruct urban spatial networks,and ana-lyzed the differences in the internal structures of each city.Different cities were calculated using urban fractal dimension and compactness index,and their external morphological characteristics of urban space were analyzed.These cities were classified into simple urban spatial forms,complex urban spatial forms,and complex urban spa-tial forms.Finally,based on the analysis results,targeted urban development suggestions were proposed for the spatial development of cities along the Grand Canal and other cities along the river.
