摘要
根据全国水资源第二次调查评价初步结果,对我国地下水水质进行了全面系统的分析,论述了地下水水化学特征。初步评价结果表明,我国地下水以重碳酸型为主,但硬度和总矿化度较大,成为影响天然水质的主要因素。地下水总体上属于中性偏碱类型。地下水水化学评价结果表明,我国地下水水质先天不足,地下水水质保护工作要重视对天然地下水水文地球化学特征的认识。
Based on water resources survey and evaluation in China, groundwater quality was systematically analyzed. The assessment of the hydrochemical characteristics of groundwater shows that most groundwater is of bicarbonate type with high hardness and TDS （Total Suspended Solids）. The pH of groundwater is mostly neutral and alkalescent. As the groundwater quality is poor naturally, the recognition of hydrogeochemical characteristics of natural groundwater is important for the groundwater quality protection.
