摘　　要：由于姜堰区浅层地下水开发利用缺乏统一的规划,并且随着开发利用规模不断扩大,可能会出现局部采补失衡的情况,研究姜堰区浅层地下水开发利用管理十分有必要。基于姜堰区水文地质条件和抽水试验所得参数,利用Visual MODFLOW软件建立姜堰区水文地质数学模型,并通过不断调试参数使模拟水位和实测水位拟合情况较好,证明建立模型合理有效,能真实地反映当地的水文地质条件,可用于姜堰区浅层地下水水位预测。以水位为控制目标,预测未来2030年姜堰区浅层地下水可开采量。结果表明,现状开采条件不变情况下,2030年姜堰区浅层地下水可开采量为467.04万m3/年;并与现状实际开采情况进行对比,分析研究区浅层地下水开发利用潜力为76.41,远远大于1.2。表明现状开采条件情况下,研究区浅层地下水仍具有一定的开采空间。因此,应严格按照浅层地下水剩余资源量分区图对研究区浅层地下水开发利用进行指导,针对有开采潜力区进行科学合理布井。Since the lack of unified planning, continuous expanding development and utilization of shallow groundwater might resulted partial imbalance in Jiangyan district. Based on the hydrogeological conditions and the parameters from pumping tests, a mathematical model of hydrogeologic in Jiangyan district was established by using Visual MODFLOW software. After continous adjustion of the parameters, the model was proved to be reasonable and effective for its good fitness on water level simulating. It can truly reflect the local hydrogeological conditions, and could be used to predict the shallow the groundwater level in Jiangyan district, and further predict the exploitable amount in future 10 years with the water level as control index. The results showed that the exploitable amount of shallow groundwater in Jiangyan district is 4.670 4 million m3/a till 2030 if current exploitation conditions unchanged. Compared with the actual exploitation situation, the exploitation and utilization potential of shallow groundwater in the study area is 76.41, which was far greater than 1.2. It indicated that under the current mining conditions, the shallow groundwater in the study area still has a certain mining space. Therefore, it is necessary to guide the development and utilization on the shallow groundwater in the study area in strict accordance with the distribution map of the remained shallow groundwater, and arrange the wells scientifically and reasonably at the potential areas.
