利用浊度监测成果概化陶家龙潭水源地水文地质特征

Generalizing Hydrogeological Characteristics of Taojia Longtan Water Source by Using Turbidity Monitoring Results

陶家龙潭水源点为地下水性质的县级以上集中式生活饮用水源地。近年来,随着水源点周围城市发展、城市建设和人类工程活动增加,水源点水质受到影响。为了对该水源点进行保护,该文利用水源点浊度指标监测资料、水源点浊度指标变化对应时段,周边区域人类工程活动记录,采用水文地质测绘、水化学方法,分析了水源点水文地质特征。结果表明:水源点受其南侧大冶组二段(T_(1)d^(2))地层岩溶管道系统中地下水直接补给,具有岩溶管道规模大、地下水流速快等特点。分析结果为周围区划建设提供了参考依据,有助于水源点的保护。

Taojia Longtan water source is a centralized drinking water source at or above the county level with the nature of groundwater.In recent years,with the increase of urban development,urban construction and human engineering activities around the water source,the water quality of the water source has been affected.In order to protect the water source point,this paper analyses the hydrogeological characteristics of the water source point by using the monitoring data of the turbidity index of water source point the corresponding period of the change of turbidity index of the water source point the records of human engineering activities in the surrounding area,and using hydrogeological mapping and hydrochemical methods.The results show that the water source point is directly recharged by the groundwater in the karst pipeline system of the second member of Daye Formation(T_(1)d^(2))on its south side,which has the characteristics of large-scale karst pipeline and fast groundwater velocity.Analysis results provide a reference basis for surrounding zoning construction,which can help protect water sources point.
