摘要
保障饮用水安全是关系民生和社会发展的一项重要工程。以甘肃省高台县备用水源地为工程背景,在野外实地调查的基础上,对研究区地下水的埋藏分布、补径排条件、水化学特征以及水位动态特征进行了分析和研究,最后并对研究区水源地选址方案进行了论证和评价。研究结果表明:高台县境内地下水水源地主要对平原区松散岩类孔隙水进行开发和利用;方案二选址区地下水类型为松散岩类孔隙潜水,地下水水质良好,含水层厚度大,储存量丰富,取水保证程度高,基本符合城市水源地建设的条件,可将其作为高台县备用水源地选址区。通过对研究区备用水源地选址方案的评价和论证,可以为高台县地下水取水水源地的进一步开发和利用提供科学依据。
Safeguarding the safety of drinking water is an important project related to people’s livelihood and social development.Based on the background of the reserve water source in Gaotai County of Gansu Province,based on the field investigation in the field,the burial distribution,the conditions of the drainage,the hydrochemical characteristics and the water level dynamic characteristics of the groundwater in the study area were analyzed and studied.The site selection scheme for the water source area was demonstrated and evaluated.The results show that the groundwater source in Gaotai County mainly develops and utilizes the loose rock pore water in the plain area;the groundwater type in the site selection site is loose rock pore diving,the groundwater quality is good,the aquifer thickness is large,and the storage is abundant.The water supply guarantee is high,and it basically meets the conditions for urban water source construction.It can be used as the alternate water source site selection site of Gaotai County.Through the evaluation and demonstration of the site selection scheme of the alternate water source in the study area,it can provide a scientific basis for the further development and utilization of groundwater abstraction source in Gaotai County.
