Evaluation of Water Use Efficiency and Fairness of Guanzhong Plain Urban Agglomeration in the Yellow River Basin
In order to improve the water use efficiency and fairness of urban agglomerations and promote ecological protection and high-quality development in the Yellow River Basin,the Guanzhong Plain urban agglomeration was taken as a case.On the basis of analyzing the sustain-able utilization level of water resources by using the water footprint and water planet boundary,the super-efficiency SBM model and the GML index were used to explore the water use efficiency of the urban agglomeration.And Gini coefficient and contribution coefficient were estab-lished to evaluate the impact of water use fairness on urban agglomeration.The results show that the water footprint,water deficit and grey wa-ter footprint of Guanzhong Plain urban agglomeration decrease by 4.52%,3.62%and 59.79%,respectively.The unsustainability of water re-sources and water pollution has been improved.The water use efficiency is insufficient and does not show the growth trend.The positive inter-action between technical efficiency and technical progress has not been achieved.The water resources occupation is relatively fair,but the fairness degree between water pollution and urban development,water carrying capacity decreases significantly.
