尺度·密度·速度:“十三五”时期超大城市面临的难题与挑战

Scale, Density, Speed: Metropolitan Problems And Challenges In The 13th Five Year Period

常住人口规模超过千万的超大城市,其空间尺度、建设密度和运行速度已达到一个前所未有的程度,甚至面临"失控"的局面。文章从衡量城市宏观结构与效率的三个基本维度—尺度、密度和速度,探讨超大城市"十三五"时期面临的难题和挑战,为规划技术和管理机制的变革寻找方向与出路。

Ten million above population cities have reached an unprecedented height in spatial scale, building density, and operation speed, and face risk of loss of control. The paper studies the problems and challenges of metropolis in the 13 th five year period from scale, density, and speed, and seeks new ways for planning technique and management.
