Spatial-temporal Evolution and Mechanism of Coupling Coordination Degree of Urban-rural Integration in Anhui Province
摘要
Abstract
County is an important carrier of urban-rural integration and rural revitalization,and coupling coordination is an important symbol of regional coordinated development.In this paper,an evaluation index system of urban-rural integration is constructed.The coupling coordination degree model,spatial autocorrelation and trend surface analysis are used to quantitatively measure the spatial-temporal evolution process of the coupling degree and coupling coordination degree of urban-rural integration in Anhui province from 2010 to 2020.In addition,the geographic detector model is used to explore the factors affecting urban-rural integration and the degree of influence.The results show that:first of all,from 2010 to 2020,the coupling degree and coupling coordination degree of urban-rural integration showed a trend of decreasing first and then increasing,but the fluctuation range was small on the whole.The variation of coupling degree of each county and district showed a phenomenon of"convergation-dispersive-aggregation"and"eastward and southward",and for the districts and counties with slightly misadjusted coupling coordination degree,it showed a trend of decreasing gradually.The phenomenon of lock-in of regional low value appears,which is mainly distributed in northern Anhui.Secondly,from the perspective of different regions,the coupling coordination of urban-rural integration in northern Anhui,central Anhui and southern Anhui increased slightly first and then continuously increased in 2015 as the turning point.Among them,the regional coordination difference in southern and northern Anhui tends to decrease linearly.The regional differences in middle Anhui showed fluctuation development.On the whole,the coupling coordination of urban-rural integration presents a spatial pattern of"low in the north and high in the south-low in the west and high in the east".With the passage of time,a new stepped pattern was formed in the cold spot area north of the Huaihe River and the hot spot area south of the Yangtze River.Finally,PM2.5 concentration,per capita GDP,river basin,total power of agricultural machinery,proportion of agricultural output value,forest coverage rate,per capita electricity consumption in rural areas,urbanization rate,and per capita disposable income ratio of urban and rural areas are the main factors affecting the coupling and coordinated development of urban-rural integration in Anhui province.关键词
