杭州城市蔓延评估体系及其治理对策

在快速城市化中,中国的城市蔓延现象日益突出.在分析城市蔓延的概念和基本特征的基础上,探究了中国城市蔓延与西方城市蔓延的区别,并发现城市蔓延与经济社会的发展息息相关.因此,先从传统的空间形态角度,在借鉴和综合多种西方城市蔓延评估方法的基础上,利用层次分析法来初步构建城市蔓延的评估体系,再从经济社会的角度,运用主成分分析和模糊数学法求出经济发展和社会生活之间的协调度,利用有关协调度的函数来对评估体系的进行修正.然后,具体以杭州市为例进行了实际测算,结果表明杭州的城市蔓延处于较严重的等级,这与从空间形态图上的判断基本一致.最后,在分析杭州城市蔓延产生原因和结合我国实际的基础上,对城市蔓延问题的治理机制进行了初步探讨,从经济增长模式、投资模式、征地补偿、城市交通和规划制定与实施等多个方面提出了相应的政策建议.
