泥河湾盆地东部地处半干旱地区,地下水资源分布不均,水质优劣不一。根据含水介质的不同该区地下水可以划分出松散岩类孔隙水含水岩组和基岩裂隙类含水岩组两大类,并依据地层岩性进一步划分为7个含水岩组。据野外调查采样分析资料,在不同赋存条件下区内地下水的水质与水量具有较大的差异,以山前洪积扇、湖滨相沉积和岩溶裂隙水质量最好,湖心相沉积最差,其中有的不符合饮用水标准,需要进行合理的开发利用规划。
The eastern part of the Nihewan Basin is located in a semi-arid area with uneven distribution of groundwater resources and uneven water quality. According to the different aqueous medium, the groundwater in this area can be divided into two categories: loose rock type aquifer pore water and bedrock fissure type aquifer, and further divided into seven aquifer groups according to formation lithology. According to field investigation and sampling analysis data, the water quality and water quantity of groundwater in the area are quite different under different occurrence conditions. The water quality of the alluvial fan, lacustrine facies and karst fissure in the foreland is the best, and the sedimentation of the lake core is the worst , Some of which do not meet drinking water standards, the need for rational development and utilization planning.
