Analyzing the hydrological response of mining activities in the Loess Plateau will help to promote ecological protection and high-quality development in mining areas. This paper selected four typical small watersheds of Baima River, Songta River, Xinshui River and Zhouchuan River on the Loess Plateau, and conducted a study on the applicability of 8 base flow segmentation methods in the Loess Plateau. The difference of anomaly cumulative percentages (DACP) based on paired watersheds was employed to analyze the impact of mining disturbances on the base flow process in the basin. The results show that the Chapman-Maxwell filtering method and the Eckhardt filtering method have the best applicability in the typical small watersheds of the Loess Plateau, the segmented base flow is relatively stable, and the base flow hydrograph conforms to the precipitation and runoff mechanism and the water regression process of the watershed; The base flow of the four small watersheds showed significant downward trends from 1956 to 2012 as a whole; With the increase of mining disturbance intensity, the DACP index of base flow increased, and mining disturbance increased the base flow of the basin.
