河流阶地型城市空间结构度测——以四川省绵阳市为例

URBAN SPACE STRUCTURE MEASURE WITH THE RIVER AND UPLAND——THE CASE OF MIANYANG,SICHUAN

应用分形理论对绵阳市城市形态近50年动态变化进行了尝试性的定量分析,揭示了绵阳市在不同历史时期分维值的变化特征。以此说明河流阶地型城市形态的空间历史演变在一定时间段上具有自相似性,城市是具有时间序列的分形体,为预测未来的城市空间发展方向提供新的手段。

By giving a quantitative analysis over urban structure in Mianyang city in the theory of fractal during the past fifty years and illustrating the changing feature of fractal dimension in different historical periods,the paper exposes the river and upland urban space structure history development is characteristic of self-comparability.And a city is chronological fractal object.All the above provide a new method for predicting the developing direction of future urban structure.
