A recent correlation of stream geomorphic indices to fault activity has revealed that stream geomorphologies in bedrock mountain areas are good records of local fault movements. The Daqingshan piedmont fault is one of the main active faults in the fault system on the northern margin of the Hetao Basin and has produced frequent large-scale earthquakes since the Late Pleistocene. In the present study, following the segmentation regime of previous studies, we divide the fault zone into five segments, namely, the Baotou, Tuyouqi West, Tuzuoqi West, Bikeqi, and Hohhot segments, and we discuss the relationship between the drainage basin geomorphology and the piedmont fault activity in the Daqingshan area using 30 m spatial resolution Shuttle Radar Topography Mission (SRTM) digital elevation model (DEM) data. We use a range of geomorphic indices to examine the drainage basins in the Daqingshan area, including the channel steepness index (k_sn), slope, hypsometric integral (HI), relief degree of land surface (RDLS), and stream lengthgradient index (SL), extracted with ArcGIS and MATLAB, and we also consider local lithologic and climate aspects. Furthermore, we compare the geomorphic indices with the slip rates of individual segments of the Daqingshan piedmont fault and paleoseismic data. The results show that the geomorphic indices of drainage basins in the Daqingshan area are primarily affected by the piedmont fault activity in the Daqingshan area. The geomorphic indices also demonstrate that piedmont fault activity has been the most intense in the middle segment of this fault system since the Late Quaternary and decreases towards the two sides.

溪流地貌指数与断层活动的最新关系表明，基岩山区的溪流地貌是局部断层运动的良好记录。大青山山前断裂是河套盆地北缘断裂系统中的主要活动断裂之一，自更新世以来一直引起频繁的大规模地震。在本研究中，根据先前研究的分割机制，我们将断层带划分为包头段，图尤奇西段，图佐齐奇段，比克其段段和呼和浩特段五段，并讨论了流域盆地地貌与断层之间的关系。利用30 m空间分辨率的航天飞机雷达地形任务（SRTM）数字高程模型（DEM）数据，对大青山地区的山前断层活动进行了研究。（k _sn），坡度，水势积分（HI），地表起伏程度（RDLS）和河流长度梯度指数（SL）（使用ArcGIS和MATLAB提取），我们还考虑了当地的岩性和气候方面。此外，我们将地貌指数与大青山山前断裂的各个部分的滑移率和古地震数据进行了比较。结果表明，大庆山地区流域的地貌指数主要受大庆山地区山前断裂活动的影响。地貌指标还表明，自第四纪晚期以来，山前断层活动一直是该断层系统中段最强烈的活动，并向两侧减小。
