广西北部湾经济区城市群城市综合承载力评价研究

Research on Urban Synthetic Carrying Capacity Evaluation of the Urban Agglomeration of Guangxi Beibu Gulf Economic Zone

本文以广西北部湾经济区城市群的6个城市为研究对象,根据指标构建的原则,选取土地、水资源、交通、环境和人口要素承载力指标,建立城市综合承载力评价指标体系。通过综合评价和比较分析,主要得出如下结论:城市群各城市承载力空间差异显著;南宁城市承载力亟待全面提升;环境承载力是影响城市群综合承载力提升的第一因素,但不占绝对主导地位;城市群发展的短板是水资源;城市群城市综合承载力整体呈下降趋势,尤其以北海下降幅度最大。针对上述问题,对城市群的可持续发展提出一些建议。

After choosing six cities of the urban agglomeration of Guangxi Beibu Gulf economic zone as the research object,this paper selects land,water,transportation,environment and population carrying capacity index and establishes comprehensive evaluation index system according to some principles.By overall evaluation and contrast analysis,the results show that urban carrying capacity has significant difference in space;urban carrying capacity of Nanning still needs to be improved comprehensively;environment carrying capacity become the most important factor that influenced synthetic carrying capacity of urban agglomeration,but not absolutely leading one;water is a soft spot for urban agglomeration development;in view of the overall situation,urban carrying capacity has shown a sharp decline,especially Beihai.To solve these problems,some measures are put forward for the sustainable development of urban agglomeration.
