Study on the Degree of Coordination of Water Resources Coupled with Economy Society and Environment in Hebei Province:Based on the Perspective of Renewable Water Utilization
As a supplement to traditional water resources,developing and utilizing recycled water can relieve the problem of the shortage of water resource and supply-demand contradiction of Hebei Province.Based on the perspective of renewable water utilization,this study investigates the mutual influence relationship between water resource utilization,economy society and environment in Hebei Province,an evaluation index system for the renewable water-economic society-traditional water resources-environment(RETE)system has been constructed.The level of development of the RETE system has been evaluated by entropy method.The degree of coupling coordination of the RETE system and their influencing factors are enquired by using coupling coordination model and gray correlation analysis.The results indicate that the development level of renewable water,economic and social,traditional water resources and environmental subsystems in Hebei Province is on an upward trend,and there is some regional variability;The coupled harmonization of the RETE system is increasing year by year,and other cities stand in the phase of coupling and coordination,except for Baoding,Cangzhou,and Hengshui,which are on the verge of dislocation;In addition,the main factors influencing the coupling and coordination degree of the RETE system are the urbanization rate,the sewage rate,the greening coverage rate of the built-up area,disposable income per urban resident and GDP per capita.
