Abstract:: Based on the analysis of the current situation and problems of water resources utilization in the Yellow Ｒiver Basin，this study examined the related concepts of utilization rate of water resources，and put forward the index of " net-utilization ratio of water resources" to represent the development and utilization of water resources in the Yellow Ｒiver Basin． Super-SBM model was further used to quantify utilization rate of water resources in the Yellow Ｒiver Basin，and an adaptation model was constructed by combining Tapio theory to explore the decoupling state between water resources utilization and economic development． The restrictive factors and ways to improve the utilization level of water resources in the Yellow Ｒiver basin were discussed． The results showed that: ① In 2020，the utilization rate of water resources in the Yellow Ｒiver Basin was 65%，and the net-utilization rate of water resources was 58%． Although the actual water resources utilization intensity is not as high as imagined，the development and utilization of water resources in the basin was still in an excessive state． ② The overall level of water resources utilization in the Yellow Ｒiver Basin showed an upward trend during the study period，and the spatial pattern of " higher in the lower reaches than in the middle reaches than in the upper reaches" was generally presented in the nine provinces． Different development patterns and characteristics led to the differences of water resources utilization in different regions． ③ The influencing factors of water resources utilization level were mainly divided into industrial structure，scientific and technological level，policy regulation，economic development and water conservancy facilities construction． Finally，corresponding improvement approaches were proposed for the influencing factors.
