【摘要】 解析黄土高原地区采矿活动的水文响应有助于促进矿区生态保护和高质量发展，选取黄土高原白马河、松塔河、昕水河和州川河四个典型小流域，研究了8种基流分割方法在黄土高原的适用性，并采用基于对比流域的距平累积差值曲线法(DACP)分析了采矿扰动对流域基流过程的影响。结果表明，Chapman-Maxwell滤波法和Eckhardt滤波法在黄土高原典型小流域中适用性最佳，分割基流量相对稳定，基流过程线符合流域的降水产流机制和退水过程；1956～2012年四个小流域的基流量整体呈显著下降趋势；随着采矿扰动强度增加，基流的DACP指数上升，采矿扰动增加了流域基流量。更多还原

【Abstract】 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.更多还原
