黄河流域县域城乡融合发展测度、时空特征及影响因素研究OACHSSCD

County-level areas serve as vital spatial links between urban and rural areas.Assessing the level of integrated urban-rural development in the Yellow River Basin and analyzing its spatio-temporal characteristics and influencing factors are of great significance for promoting ecological conservation and high-quality development in the basin.Taking 258 counties in the Yellow River Basin from 2015 to 2022 as the research sample,this study constructs an evaluation indicator system centred on five dimensions:demographic,social,economic,spatial and ecological,and employs a projection-tracing model for measurement.Furthermore,utilizing the Dagum Gini coefficient,trend surface analysis,standard deviation ellipses and the optimal-parameter geographic detector,the study investigates the spatial disparities,spatiotemporal characteristics and influencing factors of urban-rural integrated development at the county level.The results indicate:1)The level of urban-rural integrated development across counties in the Yellow River basin,as well as the levels across various dimensions,have all risen steadily,the region exhibits a gradient distribution pattern in which the downstream area outperforms the middle reaches,and the middle reaches outperform the upstream area.2)Spatial disparities in urban-rural integration across counties in the Yellow River Basin generally show a fluctuating yet converging trend,with these disparities primarily stemming from inter-regional differences,of which those between the upper and lower reaches are the most pronounced.3)The spatial variation in urban-rural integrated development across counties in the Yellow River Basin exhibits distinct east-west characteristics,with high-value areas primarily concentrated in the middle and lower reaches,whilst low-value areas concentrated in the ecologically fragile upper reaches,Over the study period,the spatial centre of gravity shifted slightly towards the south-west.4)Terrain undulation,the level of land urbanization,per capita total retail sales of consumer goods,the urbanization rate,per capita GDP and the ratio of urban to rural per capita income have strong explanatory power regarding the spatial differentiation in the urban-rural integrated development of counties in the Yellow River Basin.furthermore,the interaction between these two factors is greater than the effect of either factor alone.The findings of this study may serve as a reference for the categorized promotion of urban-rural integrated development at the county level in the Yellow River Basin.
