In order to study the influence of the tectonic activity of the Tanlu fault zone （Anhui section） on the morphology and development characteristics of the surrounding surface water system, based on the DEM data, this paper studies the geometrical distribution characteristics of the water system around the Tanlu fault zone （Anhui section） by using the GIS spatial analysis function combined with the tectonic movement characteristics of the Tanlu fault zone. Our research shows that the Tanlu fault zone （Anhui section） has a staggering effect on the surface water system in the region during different geological history periods. Influenced by the left-lateral strike-slip movement during the Triassic to the Cretaceous, the two secondary water systems intersected the fault at approximately right angles and left-turned in the Dabie Mountains from the northwest to the southeast through the main trunk fault and the secondary fault. The Wan River Basin in the Dabie Mountain area and the water system of the Huayang River Basin have been affected by the anti-rightward translational movement of the Tanlu faults since the Quaternary. Their flow directions have greatly turned from southeast to southwest, showing a right-handed twist. The right-handed dislocations also occur in the water system of the Chaohu Lake Basin due to the Wuhe fault and the Shimenshan fault. In addition, due to the influence of the Hefei Basin and the mantle-type Jiashan Basin formed by the tectonic movement of the Tanlu fault zone, the main channel of the Chi River developed along the subsidence zone on the east side of the Hefei Basin and the Jiashan Basin between the Shimenshan fault and the Jialu fault.
