湖南“3+5”城市群城市综合承载力评价

本文以湖南省"3+5"城市群为研究对象,从人口、经济、资源、环境、城市基础设施以及外部支撑力6个方面入手,建立评价指标体系,利用信息熵方法对"3+5"城市群城市综合承载力进行了评价。结果表明"3+5"城市群城市综合承载力呈现出明显的梯度差异,长沙市以综合得分1.715分居于城市群之首,益阳市为1.410分最低,且"3+5"城市群承载力总体状况不容乐观;从城市综合承载力承载力各要素来看,经济承载力是制约城市群城市综合承载力提高的首要因素;资源、环境承载力低下成为城市群共同问题;科技创新与区际交流对城市综合承载力提升具有重要意义。

Evaluation on Urban Comprehensive Carrying Capacity of "3+5" Urban Agglomeration of Hunan Province

＂3＋5＂ Urban Agglomeration of Hunan Province is a object for researching in this paper,and authers have established the evaluation index system from the population,economy,resource,environment,urban infrasture as well as external support force,and the urban comprehensive carrying capacity have been evaluated by using of entropy method .The results show that the urban comprehensive carrying capacity of ＂3＋5＂ Urban Agglomeration is a significant gradient difference, scoring 1.715 in Changsha in an integrated group of the first separation from the Town, Yiyang City, 1.410 points for the lowest, and the carrying capacity of ＂3＋5＂ urban agglomeration can not be optimistic about the overall situation. Economic carrying capacity is the primary restricting factor to improve the carrying capacity,It is a commen problem for the poor carrying capacity of resource and environment to ＂3＋5＂ Urban Agglomeration . Also it is significant to do technological innovation and districtal exchanges to upgrade the urban comprehensive carrying capacity.
