摘　　要：以地质调查项目为依托,对淮河流域内4 000余组浅层地下水样品测试结果进行评价分析。评价依据为地下水污染调查评价技术要求和地下水质量标准。结果显示,淮河流域浅层地下水中As检出较多,超标严重,超标率9.76%,Hg、Cr6+检出率和超标率稍低。分析认为,Hg、As有原生成因,也有人为活动影响成因,Cr6+主要由人为活动造成。在评价研究基础上,针流域内农村居民饮用水和农业灌溉用水两种用途,提出了开发利用地下水的建议,为区域农业生产、农村经济发展规划提供了依据。This paper shows the outcome of data analysis with more than 4000 shallow groundwater samples in Huaihe Catchment based on Geological Research Program. Data analysis and evaluation is in accordance with Technical Requirements of Groundwater Contamination Research and Evaluation and Quality Standard of Groundwater. The As＇ content in shallow groundwater is high, the content of Hg, Cr^6 ＋ is lower, and 9.76% of the groundwater samples is worse with As. Hg and As come from protogenesis earth and human beings＇ pollution, Cr^6＋ is just from human beings＇ pollution. On the basis of the outcome of data analysis and evaluation, the author gives some suggestions about groundwater development and utilization in agricultural area, which should be useful and important reference for local government in agricultural plan and production.
