The utilization rate of water resources in the Haihe basin is high, and there are no large floods over last few decades.A few of human activities such as water resources exploitation, water and soil conservation, urbanization, have significant impacts onthe hydrological characteristics in the Haihe basin, which is one of the most influential basins in the seven major basins. This pa -per analyzed the changing trend of the underlying surface in the Haihe basin and its influence on the production flow and conflu -ence flow. In addition, the paper studied the revision method of hydrology results, and achieved the results of hydrology revision.On this basis, the paper summarized the existing problems on the hydrological revision results in the Haihe basin and provided thesuggestions for the future work.
