Spatio-temporal pattern and influencing factors of the coupling coordination of new urbanization and water ecological environment in the Yellow River Basin
Clarifying the coupling relationship between urbanization and water ecological environment and its influencing factors has great significance for promoting the ecological protection and high-quality development of the Yellow River Basin.Based on the analysis of the coupling mechanism between new urbanization and water ecological environment,this paper analyses the spatial and temporal pattern of the coupling between the two sys-tems and its driving factors by using the coupling coordination degree and spatial econometric model.The main conclusions are as follows:(1)From 2006 to 2021,the coupling coordination degree between new urbanization and water ecological environment in the Yellow River Basin had improved steadily but were overall low,which had risen from the stage of near imbalance to the stage of primary coordinated in general.Meanwhile,the cou-pling coordination degree of the downstream is greater than that of the middle reaches and upstream.(2)The cou-pling coordination degree has a significant spatial spillover effect,and the influence strength of the spatial spill-over effect from high to low is the lower,middle and upper reaches of the Yellow River respectively.(3)Local government capacity has a positive promotion on the local coupling coordination but a negative spillover effect on that of neighboring cities;Local population agglomeration and environmental regulation negatively affect its own coupling coordination;Capital accumulation positively influences the coupling coordination of the whole study area through positive spillover effect,while with a negative influence in the downstream;The level of in-dustrialization hinders the coupling coordination development in the whole basin through negative spillover ef-fect;The open and innovative economy has positive impact and spillover effect only on the middle reaches.Dif-ferentiated strategies should be adopted to promote the coupling coordination development of new urbanization and water ecological environment across the Yellow River Basin.
