中原城市群“三生”功能耦合协调 时空演变及其影响因素分析

基于2005－2020年社会经济统计数据,结合线性加权回归、空间自相关以及地理探测器等模型探究中原城市群生产－生活－生态功能之间的互动关系、时空演变特征以及影响因素。结果表明:研究期内中原城市群"三生"功能耦合度呈现整体上升趋势;研究区域"三生"功能耦合协调发展呈现出明显的空间自相关性;人均地区生产总值、就业人数占比、土地垦殖率、城镇(农村)居民人均可支配收入、区域空气质量指数以及生活垃圾无害化处理率是影响中原城市群"三生"功能耦合协调性的主要影响因素,且同一影响因子在不同时间段的探测结果具有显著的差异性。

Spatial-Temporal Evolution of the Coupling Coordination of "Production-Living-Ecology" Functions in Central Plains Urban Group and Its Influencing Factors

Based on the socio-economic statistical data from 2005 to 2020, and with the help of linear weighted regression, spatial autocorrelation and geographic detector models, this paper explores the interaction between production-living-ecology functions of the central plains urban group, the characteristics of spatial-temporal evolution and its influencing factors. The results show that the coupling degree of the "production-living-ecology" functions of the central plains urban group shows an overall upward trend during the study period; The coupling and coordinated development of "production-living-ecology" functions in the study area shows obvious spatial autocorrelation; The main influencing factors that affect the coupling coordination of the "production-living-ecology" functions in the central plains urban group include the per capita GDP, the proportion of employed people, the land reclamation rate, the per capita disposable income of urban (rural) residents, the regional air quality index and the harmless treatment rate of domestic waste, while the influence of the same factor in different periods of time shows significant difference.
