广西北部湾经济区城市群综合承载力时空格局及制约因素

Spatio-temporal pattern and constraint factors of urban comprehensive carrying capacity in urban agglomeration of Guangxi Beibu Gulf Economic Zone

对广西北部湾经济区城市群城市综合承载力进行研究,可以加快其新型城镇化进程和促进城市群可持续发展,为有关部门提供决策参考。选取人口、资源环境、社会发展、经济发展承载力指标构建广西北部湾经济区城市群城市综合承载力评价指标体系,运用熵值法对其进行综合评价。结果表明,广西北部湾经济区城市群城市综合承载力呈稳步上升趋势,水平较低且具有分级现象;各要素承载力年际变化趋势差异和空间差异明显。提出从整体上优化城市综合承载力结构、保护资源环境和增强科技创新,同时根据各市制约因素的不同因地制宜提升城市综合承载力。

Studying the urban comprehensive carrying capacity of urban agglomeration of Guangxi Beibu Gulf Economic Zone can speed up its new urbanization process and promote the sustainable development of urban agglomerations,and provide decision-making reference for relevant departments.The population,resources and environment,social development,economic development carrying capacity index was selected to establish comprehensive evaluation index system of urban comprehensive carrying capacity of Guangxi Beibu Gulf Economic Zone,and the comprehensive evaluation was carried out by entropy method.The results showed that urban comprehensive carrying capacity of Guangxi Beibu Gulf Economic Zone were steadily increased,had a steady upward trend,with low level and grading phenomenon;The inter-annual variation trend and and the spatial difference of each factor of carrying capacity were obvious.It was proposed to optimize the overall urban carrying capacity structure as a whole,protect the resource environment and enhance scientific and technological innovation,and improve the urban comprehensive carrying capacity according to the different local constraints.
