Analyzing the dynamic evolution and current situation of development and utilization of water resources is of great significance to the sustainable development and protection of water resources. The data of 1997-2020 water resources bulletins of 10 water resources zones, including Songhua River, Liao River, Hai River, Yellow River, Huai River, Yangtze River, Southeast China, Pearl River, Southwest China, and Northwest China, were selected to analyze the dynamic evolution of water resources and the current situation of development and utilization in these zones by using Kendall rank test. The results show that there are spatial differences in the dynamic evolution of water resources in China with the Yellow River region showing a highly significant increasing trend, the Songhua River basin showing a significant increasing trend, the Huai River basin showing a non-significant decreasing trend, and the rest of the basin showing a non-significant increasing trend. The Songhua River and Yangtze River basin show a weakly significant increasing trend, while the Liao River, Hai, Huai and Southeast rivers basin show a non-significant decreasing trend; The other water resources basin all show a non-significant increasing trend. The proportion of surface water is the largest, groundwater is the second largest and other water uses is the smallest. The water consumption of agriculture and industry in China's water use structure is on a highly significant downward trend after 2013, which corresponds to an increase in the efficiency of water use in agriculture and industry, a stable level of water use in domestic use and an increase in ecological water use year by year.
