In order to evaluate the sustainable utilization level of water resources in the nine provinces(autonomous regions)of the Yellow River Basin,improve the status of water resources and realize the sustainable utilization of regional water resources,this paper proposed a comprehensive evaluation index of sustainable utilization of water resources suitable for the nine provinces(autonomous regions)of the Yellow River Basin based on the water footprint model.Spearman correlation analysis and multiple linear regression analysis were used to ana-lyze the driving factors of sustainable water resources utilization in the nine provinces of the Yellow River Basin.The results show that the wa-ter resources footprint of the nine provinces(autonomous regions)in the Yellow River Basin from 2010 to 2020 increases first and then de-creases in a small amplitude,and the water environment footprint shows a decreasing trend,and the spatial distribution of water resources footprint and water environment footprint is very uneven.In the nine provinces(autonomous regions)of the Yellow River Basin,the level of sustainable utilization of water resources has increased to different degrees.The level of sustainable utilization of water resources in the up-stream provinces(autonomous regions)is higher,while the level of sustainable utilization in the middle and downstream provinces(autono-mous regions)is lower.The main driving factors of sustainable water resources use are population density,wastewater treatment rate and the proportion of secondary industry,followed by per capita water consumption and fertilizer application intensity.
