榆林市阴塔水源地水文地质调查

Hydrogeological Investigation of Yinta Water Source Area in Yulin

通过对陕西省榆林市府谷县阴塔水源地水文地质进行勘查,研究该区地形地貌、水文地质及地层分层、地质构造等基本问题,研究了其含水层厚度、岩性、富水性等。借助抽水试验勘定水源地边界,划分水量丰富区、水量较丰富区、水量中等区;水动态观测包括地下水动态观测和黄河水的动态观测,观测的项目包括水位、水质等,将其与该地区的年降水量进行对比分析,查明区内地下水动态规律,确定地下水动态类型、黄河水渗影响范围,为研究区水资源利用和经济建设提出合理的水资源开发建议。

Based on the hydrogeological exploration of the water source area of Yinta in Fugu County, Yulin City, Shaanxi Province, the basic data of topography, hydrogeology, stratigraphic division and geological structure are studied. The regional aquifers are dominated by the Upper Triassic sandstone and Quaternary deposits, and the aq- uifer thickness, lithology and water are identified. By means of pumping water test, the boundary of water source, water rich region and water abundance area, water medium area are determined. Dynamic observation of water in- eluding underground water and Yellow River water about water level, water quality, etc., are carried out to compare with the annual precipitation, with the aim of finding out the groundwater dynamic law and determining the ground- water dynamic type and the Yellow River water impact area. Some reasonable suggestions of water resources utiliza- tion and water resources development for economic construction are also put forward.
