在分析城市综合承载力内涵基础上,通过建立评价指标体系,运用函数模型计算2015年中国地级以上城市综合承载力水平,利用探索性空间数据分析方法探讨了地级以上城市综合承载力的空间分布特征。结果表明:中国地级以上城市综合承载力存在较大差距,整体呈现从东部沿海向西部内陆递减的空间分布趋势;地级以上城市综合承载力呈现明显正向全局空间自相关关系,从局域空间自相关和冷热点结果来看,呈现出自东向西由热点逐步过渡为冷点的空间格局,HH型城市主分布在热点区,H-L型城市以西部地区直辖市和省会城市居多,L-H型城市数量只有河源市,L-L型城市集中分布在冷点区。研究结果可为解决当前城镇化问题、推进新型城镇化进程提供指导和借鉴。
The comprehensive carrying capacity of cities is the embodiment for evaluating whether a city has the ability of comprehensive development, and increasing the comprehensive carrying capacity has important practi- cal significance to promote the new urbanization process. As a special economic, social, resource and environ- ment complex system with the characteristics of dissipative structure, the city has a continuous exchange of mate- rial energy with the outside world in the process of its formation and development. In this process, the city system not only enjoys economic, social and resource and environmental factors on the supporting role of its develop- ment, but also faces pressure from different factors, at the same time, as the main body of the city, people have the ability to take the initiative to make a positive response, through the role of regulation to strengthen the sup- port for different elements and to avoid the pressure of the outside world. Therefore, the comprehensive carrying capacity of the city can be regarded as the coupling function of the support, the pressure and the control force pro- duced by different factors. The evaluation index system and function model are established from three aspects: the pressure, the supporting force and the control force of the city, making a scientific evaluation of the compre- hensive carrying capacity of cities at prefectural level and above in China 2015, and exploring the spatial distribu- tion characteristics by using the exploratory spatial data analysis method. Through the further study, we can draw- ing the following conclusion: Overall, the comprehensive carrying capacity level at prefecture level and above in China is low, and there is a big difference of the comprehensive carrying capacity between different cities at pre- fecture level and above in China, presenting a tendency of decrease from east coast to the west inland on the whole. Through the further analysis of spatial distribution characteristics, finding cities at prefecture level
