甘肃省城镇化与基本公共服务时空格局及耦合关系

Spatial-temporal Pattern and Coupling Relationship between Urbanization and Basic Public Services in Gansu Province

城镇化对推进基本公共服务空间格局的发展发挥着重要作用,基本公共服务水平的提高也可以促进新型城镇化的健康发展,二者的耦合协调程度反映了城镇化进程中对城镇化质量的新要求。以甘肃省为例,运用熵值法、耦合协调度模型、相对发展模型探讨2010-2019年城镇化与基本公共服务时空演进特征以及二者相互作用关系。结果表明:甘肃省城镇化与基本公共服务总体水平呈逐年上升趋势,空间格局分异明显;甘肃省各个城市的耦合协调度分布呈“金字塔型”且不断优化,耦合系统先后经历了低水平耦合-拮抗-磨合-高水平耦合阶段;甘肃省耦合协调水平与相对发展类型具有较强的空间响应关系。在此基础上提出促进甘肃省城镇化与基本公共服务协调发展的对策建议。

Urbanization plays an important role in promoting the development of the spatial pattern of basic public services.The improvement of the level of basic public services can also promote the healthy development of new urbanization.The degree of coupling and coordination between the two reflects the new requirements for the quality of urbanization in the process of urbanization.Taking Gansu Province as an example,entropy method,coupling coordination degree model,relative development model and other methods are used to explore the spatial and temporal evolution characteristics of urbanization and basic public services from 2010 to 2019,as well as the interaction between them.The results show that the overall level of urbanization and basic public services in Gansu Province is increasing year by year,and the spatial pattern is significantly different.The distribution of the coupling coordination degree of each city in Gansu Province is“pyramid”and constantly optimized.The coupling system has experienced the stage of low-level coupling-antagonism-running in-high-level coupling;There is a strong spatial response relationship between the coupling coordination level and the relative development type in Gansu Province.On this basis,countermeasures and suggestions are put forward to promote the coordinated development of urbanization and basic public services in Gansu Province.
