陕北安塞-吴旗地区地下水资源测算及水质评价

陕北安塞-吴旗地区属陕北黄土高原东北缘之黄土梁峁丘陵地形.本文对陕北安塞-吴旗地区内水文地质特征、主要含水层及赋水特征进行了分析,并对地下水资源进行了测算和评价,结果表明:洛河组的水资源量最大,其次为北部沙漠-冲积平原,安塞地区河谷地下水资源贫乏;区内所有表层潜水及吴旗以东洛河组深层承压水的矿化度均小于1 g/l,可以作为饮用水源.

Measuring and Calculation of Groundwater and its Quality Evaluation in Wuqi Area of Ansai County in the Northern part of Shaanxi province

The article analyzes some hydro-geological characteristics, major aquifers and water characteristics in Wuqi area of Ansai County in the northern part of Shaanxi province. It also measures, calculates and evaluates groundwater resources. And the results show that the group of Luo river group has the largest volume of groundwater resources, the second is in the alluvial plain of north-desert, and there is short of groundwater resources in river valley of Ansai County. In the area, the mineralization of all shallow groundwater and deep water in confined aquifers of Luo river group to the east of Wuqi is less than 1g/l, which can be used as drinkable water source.
