摘　　要：通过水文地质调查及以往成果研究,分析阐述了工作区水文地质特征;基本查明了工作区地下水含水层特征和开发利用现状,完成了三口不同类型的供水井,平均单井出水量74m^3/d,水质水量满足饮用水标准,解决了3700人的生活用水基本需求。总结了三种井型的优缺点,并分析了各井型在工作区内的适用性,为今后区内地下水资源开采利用提供了技术依据。A hydrogeological survey and previous research results are employed to evaluate the hydrogeological characteristics of a study area in the Jianghuai watershed,China.The characteristics of the groundwater aquifer and its current exploitation and utilization conditions are identified.Three different types of water supply wells are employed:pipe wells,radiation wells,and compound wells.The total recoverable water is 222 m^3/d,the average single well water output is 74 m^3/d,and the maximum single well water output is 104.4 m^3/d.The aquifer meets the basic water demand of 3,700 people,as well as the drinking water standards for quality and quantity.The advantages and disadvantages of the three types of wells are summarized,and the suitability of each type is analyzed with regards to the study area.Suggestions are made regarding the selection of future well types,locations,and depths.This study provides an important reference for the future exploitation and utilization of groundwater resources.
