南阳市城区地下水系统划分及供水意义

Division of Groundwater Systems and Significance of Water Supply in Nanyang City

根据地层、水文地质条件等,把南阳市城区地下水划分为浅层、中深层、深层和超深层四个含水系统,提出分别作为城市工业冷却水、生活饮用水、天然矿泉水和医疗热矿水水源的分层开发观点。

According to the stratum and hydrogeoplgical conditions, the groundwater in Nanyang urban area can be divided into four water-bearing systems,which include shallow layer, medium-deep layer, deep layer and ultra-deep layer. Therefore the authors put forward the new viewpoint that the four systems can respectively be regarded as water sources of industrial cooling water, drinking water, natural mineral water and medical thermal mineral water for stratified exploitation.
