【摘要】：以长江中游城市群的36个城市为例,构建了经济发展、城市化、社会保障、生态环境综合评价指标体系,运用耦合度模型评估了36个城市2011~2013年的耦合度,并利用GIS技术分析系统的得分与耦合度的空间分布特征。结果表明:长江中游城市群的36个城市的经济发展、城市化和社会保障水平的空间分布比较相似,三者间存在显著的正相关关系。但是,存在显著性的地区差异。36个城市生态环境得分均值很高,城市之间差异很小。从耦合度的空间分布来看,长江中游城市群明显存在3个高耦合度的聚集区域,即长株潭城市圈,武汉-南昌(含鄂州、黄石和九江)城市带和鄂北4市,即十堰、襄阳、宜昌和荆门。最后,36个城市之间耦合度的差异呈现逐年缩小的趋势。
[Abstract]:Taking 36 cities in the middle reaches of the Yangtze River as an example, a comprehensive evaluation index system of economic development, urbanization, social security and ecological environment is constructed, and the coupling degree of 36 cities from 2011 to 2013 is evaluated by using the coupling degree model. GIS technique is used to analyze the spatial distribution of the score and coupling degree of the system. The results show that the spatial distribution of economic development, urbanization and social security level of 36 cities in the middle reaches of the Yangtze River is similar, and there is a significant positive correlation among the three cities. However, there are significant regional differences. The average score of ecological environment of 36 cities is very high, and the difference between cities is very small. From the spatial distribution of coupling degree, there are obviously three gathering areas with high coupling degree in the urban agglomeration of the middle reaches of the Yangtze River, that is, Chang-Zhuzhou-Xiangyang City Circle, Wuhan-Nanchang (including Ezhou, Huangshi and Jiujiang) urban belt and four cities in northern Hubei, namely Shiyan, Xiangyang, Yichang and Jingmen. Finally, the difference of coupling degree among 36 cities is decreasing year by year.
