Abstract: This article is based on panel data from 57 county-level administrative regions in the Yellow River basin (Gansu section) in 2009, 2012, 2015, 2018 and 2021. The coupling coordination degree model is used to calculate and analyze the coupling coordination relationship and spatio-temporal evolution law between water resources and farmland, gardens, forests, grasslands and wetlands. The results indicate:①During the research period, the coupling and coordination relationship between water resources in the Yellow River basin (Gansu section) and cultivated land, gardens, forests, grasslands, and wetlands showed different development patterns and spatial differentiation characteristics. Overall, the coupling coordination degree between water resources and grasslands, cultivated land, and gardens is relatively high, while the coupling coordination degree with forests and wetlands is relatively low. ②The overall trend of coupling and coordinated development between water resources and cultivated garden grass moisture shows a distribution pattern of low in the northeast and high in the southwest in space, with no significant fluctuations in time. ③There was no obvious trend of high coupling high coordination evolution during the research period, indicating that the spatial and quantitative distribution of various natural resources in the Yellow River basin (Gansu section) is uneven. In the future, attention should be paid to designing differentiated natural resource coordination development paths, guiding various natural resources to develop in a more orderly and coordinated direction.

Key words: Yellow River basin (Gansu section), water resources, cultivate and wet the garden grass, coupling coordination relationship
