This paper studied the coordination degree between water environment and social economy in the Yellow River basin from multiple logical and spatial dimensions. Based on the analysis of the interaction between water environment and social economy, the water environment index system of the Yellow River basin was constructed from three logical dimensions of water resources, water pollution and water governance. The coupling coordination model was used to measure the overall coordination degree between water environment and social economy in the Yellow River basin. From the three spatial dimensions of the upper, middle and lower reaches of the Yellow River basin, seven urban agglomerations along the Yellow River and 61 cities, and three logical dimensions of water resources, water pollution and water governance, this paper used Deng’s correlation degree method to measure the correlation level between water environment and social economy and explore its causes. The results show that the overall coordination degree between water environment and social economy in the Yellow River basin is low but increasing. From 2009 to 2018, the correlation degree between the three logical dimensions of water environment and social economy fluctuated between 0.7-0.8 and the spatial differentiation is not obvious. From 2009 to 2018, the correlation degree between water environment and social economy in the middle of the Yellow River basin has been increased, while the correlation degree between water environment and social economy in the upper and lower reaches of the Yellow River basin has been decreased. Taiyuan urban agglomeration shows an increasing trend and Ningxia urban agglomeration along the Yellow River decreases slightly. Among the 61 cities, it needs to focus on the cities of Longnan, Linfen and Baoji that have high correlation between water resources and social economy, the cities of Guyuan, Jincheng and Longnan that have high correlation between water pollution and social economy and the cities of Linfen, Qingyang and Bayannur that have low correlation between water management and social economy.

In order to improve the level of ecological protection and high-quality development of the Yellow River Basin, improve the level of urban capacity for disaster reduction and management and explore the coordination between urban resilience and economic development level, in this paper, nine provinces in the Yellow River Basin were selected as the research objects, and the evaluation values of urban resilience and economic development level were estimated by using entropy weight method from 2010 to 2019, and the coupling coordination between urban resilience and economic development level was discussed based on the coupling coordination degree model. The results show that a) the level of economic development in the Yellow River Basin has regional differences and the overall distribution is "high in the east and low in the west, and high in the south and low in the north". b) The overall urban resilience of the Yellow River Basin is at a low level and its spatial distribution is correlated with the level of economic development. c) The development of coupling coordination degree system shows the three routes of a growth-oriented route represented by Gansu, Qinghai and Ningxia, a steady route represented by Shanxi, Shaanxi and Inner Mongolia and a mature route represented by Sichuan, Henan and Shandong.
