摘　　要：以新一轮《全国地下水资源评价》项目为依托,以几十年地下水化学资料和水文地质资料为基础,对我国地下水质量进行了综合评价,阐述了我国地下水质量分布特征,简要分析了其成因,并提出了预防地下水水质恶化的建议。我国地下水质量总体状况较好,但局部质量低下,区域分布差异很大,是自然地理、地质、水文地质条件、人类活动等因素共同作用的结果。作者认为要想改善地下水质量就要合理开发利用地下水资源,合理布局工农业,并建立和完善地下水质量监测和预警系统。On the basis of hydrogeological and hydrochemical data of many years,comprehensive assessment of groundwater quality was carried out in this paper.Groundwater quality distribution characteristics and the causes of formation of groundwater quality were discussed,and some suggestions of preventing groundwater quality from worsening were also given.The assessment results indicate that in China groundwater is of good quality in general,worse in some areas,and a great regional diversity exists.Physical geographic,geologic,and hydrogeologic conditions as well as human activities have an conjunctive effect on the groundwater quality.Reasonable exploitation of groundwater resources,advisable distribution of industry and agriculture and foundation of groundwater monitoring and alarming system are very useful in conserving and improving groundwater quality.
