都市圈内部城市空间扩展机制研究——以南京都市圈中心城市为例

Study on the Expansion System of Urban Space within City Circle——With the Central City within Nanjing City Circle as an Example

都市圈内部城市空间扩展的影响要素分别有自然限制要素、人文指引要素、交通诱导要素和经济指向要素,它们互相作用,形成矢量模式、覆盖模式和整合模式。南京都市圈的中心城市南京市的空间扩展课题探索出一种综合型分析方法:即建立合理的综合指标体系。运用这种方法进行研究,得出南京市应以向东、向南发展为主的结论。

The influential factors of the expansion of city space within the city circle include natural limitation,human direction, traffic inducement,andeconomic direction.These factors interact on each other,forming a mode of vector,overcast and conformity.Nanjing,the central city of the Nanjing citycircle,has found a comprehensive method for analysis of its spatial expansion:to set up a reasonable comprehensive index system.Study by thismethod has come to the conclusion that Nanjing should develop eastwards and southwards.[
