In order to realize the sustainable utilization of water resources, a calculation method of water resources pressure index covering water quantity and water quality was put forward based on the clear spatial distribution law of Chinas blue water footprint and grey water footprint, and the water resources pressure situation of provincial administrative regions in China was evaluated. The results show that there are significant differences in blue water footprint among provincial administrative regions. The blue water footprint of agricultural departments in most provincial administrative regions is larger than that of other departments. Henan, Jiangsu and Shandong rank the top three in the grey water footprint. The pressure index of water resources in Ningxia, Hebei, Shandong and Tianjin is significantly higher than that in other provincial administrative regions. There are some differences between water resources pressure index distribution and grade distribution. The application of water-saving technology, the optimization of crop layout and the improvement of water-saving consciousness all contribute to the reduction of blue water footprint. Controlling the application rate of nitrogen fertilizer and increasing the utilization rate of nitrogen fertilizer are helpful to reduce the grey water footprint. Entity and fictitious water resources import helps to alleviate regional water resources pressure.
