地下水是宿迁市主要的供水水源 ,过去由于开采布局不合理 ,在全区已形成多个大小不等的降落漏斗 ,且面积在不断扩大。为了加强地下水资源的管理 ,合理开发利用和有效保护地下水资源 ,必须进行地下水资源的调查与评价。本文采用 MODFL OW模型对全区的地下水位和水量进行模拟和预报。在此基础上制定合理的开采方案 ,通过对开采量的优化和合理分配 ,在获得最大开采量的同时 ,有效地控制降落漏斗区水位的下降 ,为该地区地下水资源的合理开发利用提供了依据。
Groundwater is the main source of water supply in Suqian City. In the past, due to the unreasonable mining layout, a number of landing funnels of various sizes have been formed in the whole region and the area is continuously expanding. In order to strengthen the management of groundwater resources, rational development and utilization and effective protection of groundwater resources, groundwater resources must be investigated and evaluated. In this paper, MODFL OW model is used to simulate and forecast the groundwater level and water quantity in the whole area. On the basis of this, a reasonable mining plan is formulated. By optimizing and rationalizing the mining volume, the maximum exploitation quantity can be obtained and the water level drop in the falling funnel zone can be effectively controlled, which provides a basis for the rational exploitation and utilization of the groundwater resources in this area .
