丰县地下水超采区评价及压采可行性研究

Evaluation on groundwater over exploitation district in Fengxian County and research on pressure production feasibility

丰县是江苏省水资源严重缺乏的县市,地下水是主要的供水水源。本文在分析丰县地下水资源现状的基础上,采用地下水数值模拟技术对地下水超采区现状进行评价,指出了地下水超采导致的一系列环境地质问题。针对丰县地下水超采状况,结合地下水压采目标和方案,利用已建立的地下水评价模型对压采效果进行评价,评价结果显示:在地下水压采方案下,地下水降落漏斗将得以控制和恢复,地面沉降状况得到有效缓解。最后提出了实现地下水资源可持续利用的措施建议,为地下水资源的合理开发利用提供了依据。

Fengxian County is a county with severe water deficiency in Jiangsu Province. Groundwater is the main source of water supply. In the paper, groundwater numerical simulation technology is adopted for evaluating the status of groundwater over exploitation area on the basis of analyzing water resources status in Fengxian County. A series of environmental geological problems caused by groundwater over exploitation are pointed out. Groundwater pressure production objectives and plans are combined, the established groundwater evaluation model is utilized for evaluating the pressure production effect in view of groundwater over exploitation condition in Fengxian County. The evaluation result shows that groundwater cone of depression will be controlled and restored under the groundwater pressure production plan. The ground settlement is effectively alleviated. Finally, measures and suggestions to realize sustainable utilization of groundwater resources are proposed, thereby providing basis for rational development and utilization of groundwater resources.
