In the past 50 years, the cause of ecological problems such as land desertification in the Tarim River Basin has been caused by the interference of human activities on hydrological processes. Based on the hydrological data of the monthly time scale, the comparative analysis method was used to analyze the interference characteristics of human activities on the hydrological process of the river basin from the aspects of intra-annual process, inter-annual process and water intake process of runoff. According to the characteristics of water resources development and utilization in the study area, the interference point of human activities on hydrological processes in the river basin was calculated by using mathematical statistics method-ordered clustering method and run test method.
