摘要 
为了研究郯庐断裂带(安徽段)构造活动对其周边地表水系形态及其发育特征的影响,本文基于DEM数据,利用GIS空间分析功能并结合郯庐断裂带构造运动特征,对郯庐断裂带(安徽段)周边水系的几何分布特征进行研究。研究表明:郯庐断裂带(安徽段)在不同地质历史时期对区内地表水系产生错动影响。受郯庐断裂三叠纪到白垩纪期间左旋走滑运动影响,两条二级水系在大别山区自西北向东南流经郯庐主干断裂及次级断裂时与断裂呈近似直角相交并发生左旋错动。大别山地区的皖河流域与华阳河流域水系受郯庐断裂第四纪以来逆右行平移运动影响流向由东南向同步大幅度拐向南西,表现为右旋扭错;巢湖流域水系受五河—合肥断裂和石门山断裂影响也出现了右旋位错。此外,受郯庐断裂带构造运动形成的合肥盆地和地堑式嘉山盆地的影响,池河的主河道沿合肥盆地东侧的沉降带和石门山断裂与嘉庐断裂之间的嘉山盆地发育。

Abstract
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.
