构建了城乡子系统发展评价指标体系,建立了城乡发展协调度测算模型,对长江三角洲16个城市的城乡发展协调度进行了比较和评价。结果显示,长江三角洲城乡协调发展的空间差异显著,经济越发达的地区,城乡协调度越高,而经济发展水平越低的地区,城乡协调度越差。根据城乡协调度系数的大小,可以将长江三角洲16个城市划分为四种类型:协调型、基本协调型、初级失调型和失调型。最后,提出了促进长江三角洲城乡协调发展的对策建议。 The evaluation index system of urban-rural sub-system development was constructed, and the model of urban-rural development coordination was established. The coordination of urban-rural development in 16 cities of the Yangtze River Delta was compared and evaluated. The results show that there is significant spatial difference in the coordinated development of urban and rural areas in the Yangtze River Delta. In the more economically developed regions, the coordination between urban and rural areas is higher, while in the regions with lower economic development, the coordination between urban and rural areas is even worse. According to the size of the co-ordination coefficient between urban and rural areas, 16 cities in the Yangtze River Delta can be divided into four types: coordinated type, basic coordinated type, primary offset type, and offset type. Finally, some countermeasures are put forward to promote the coordinated development of urban and rural areas in the Yangtze River Delta.
