【摘要】：改革开放以来,中国经济发展迅速,城市化水平大幅提高,但同时也引起了城市交通拥挤、资源短缺和环境污染等城市化问题。城市综合承载力是城市可持续发展的基础,也是衡量未来城市发展潜力的重要标准,其定量化地研究对于评估城市未来可持续发展具有重要意义。以太原市为例,从城市综合承载力划分为人口、经济、社会和生态环境4个准则层,并选取了20个评价指标,建立了太原市城市综合承载力评价指标体系,运用层次分析法对太原市1985—2010年城市综合承载力的变化进行了评价分析。结果表明:太原市城市综合承载力整体上呈上升趋势,由较低承载力水平转变为较高承载力水平,1985—2010年综合承载力指数从0.3397提升到0.6444。其中,人口承载力指数逐年降低,是城市综合承载力的主要限制因素;经济、社会和生态环境承载力指数均呈上升趋势,其中,经济承载力的提高是促进城市综合承载力上升的主要驱动因素。
[Abstract]:Since the reform and opening up, China's economy has developed rapidly, the level of urbanization has been greatly improved, but also caused by urban traffic congestion. Urban comprehensive carrying capacity is the basis of urban sustainable development, and it is also an important criterion to measure the potential of urban development in the future. The quantitative study is of great significance to evaluate the future sustainable development of the city. Taking Taiyuan as an example, the comprehensive carrying capacity of the city can be divided into four levels: population, economy, society and ecological environment. And 20 evaluation indexes were selected to establish the evaluation index system of urban comprehensive carrying capacity in Taiyuan. The comprehensive bearing capacity of Taiyuan city from 1985 to 2010 was evaluated and analyzed by using AHP. The result shows that the comprehensive bearing capacity of Taiyuan city is on the rise as a whole. The comprehensive carrying capacity index increased from 0.3397 to 0.6444.The population carrying capacity index decreased year by year from the lower carrying capacity level to the higher bearing capacity level. It is the main limiting factor of urban comprehensive bearing capacity. The index of economic, social and ecological carrying capacity is on the rise, among which, the increase of economic carrying capacity is the main driving factor to promote the increase of urban comprehensive carrying capacity.
