The problem of water pollution has become one of the most important constraints on China's economic and social development, and has attracted great attention from the national and local governments. Only by fully grasping the surface water quality can it be possible to control water pollution more efficiently and effectively. This article uses the weekly data of 148 surface water automatic monitoring stations of China Environmental Total Station from 2016 to 2018 in a total of 90 periods to analyze the overall water quality situation. A detailed analysis of the watershed is carried out, and it corresponds to the province and city where the monitoring station is located, to see the impact of the difference between provinces and cities on surface water quality. The results show that the improvement of surface water quality in China is not obvious, and some rivers even deteriorate. However, the influence of provinces and cities on the change trend of water quality is not obvious. Overall, the upstream is relatively good, the midstream and downstream are poor. More pollution types need attention, and more indicators need to be included in the monitoring system.
