南京城市空间扩展的特征与机制

Study on the Urban Spatial Expansion of NANJING City

城市空间的扩展是城市生长的需求和体现。城市的形成和发展是一个时空过程 ,具有继承性 ,对一个城市的空间扩展状态的研究和对城市扩展的时空规律和动力机制的探讨可以使人们正确把握其在城市化进程中所处的阶段 ,预测城市发展趋势。本文以南京市为例探讨了其在 80年代以来城市空间扩展及结构演化的现象和特点。

The urban spatial expansion is the requirement and materialization of urban development, and the expansion is a space-time process .The research on urban spatial expansion, itsspace-time discipline and its impetus mechanism can make us to grasp the period in urbanization process of the city.
