城市紧凑度的综合测度及驱动力分析——以江苏省为例

根据紧凑城市的核心内涵,从经济紧凑度、城市用地及形态紧凑度、交通紧凑度和人口紧凑度等方面,构建城市紧凑度的综合测度模型。运用熵值法,对江苏省13中心城市紧凑度进行综合分析后认为,各中心城市紧凑度总体水平不高,且空间差异明显,大致由南向北渐次减弱,根据差异可将江苏省中心城市紧凑度划分为紧凑、较紧凑和不紧凑三类。在此基础上,提出城市紧凑度主要是制度调控力,市场拉动力、人口推动力和交通引导力共同驱动的结果,结合回归模型对主要驱动力进行比较分析,认为制度调控力,市场拉动力和人口推动力对江苏城市紧凑度影响显著,交通引导力还需要进一步强化。

Comprehensive Level and Impetus of City Compactness-A Case of Jiangsu Province

The thirty years of reform and opening are thirty years for China cities' quick development,during which many problems appeared such as the disorder of city space,inequality and deterioration of internal and external environment,and so on.Compacted city theory was advanced by European scholars to resolve such problems as city decline,city expansion as well as limiting factors of land resources,which mainly involves theoretical ideas of high density city exploitation,mixed land use,decentralized convergence,...
