摘要
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。
Ground water is main water supply in Suqian City, because exploitation and distribution are irrationality in the past, many different cones of depression have formed in whole area, and its area is extending. In order to reinforce ground water resource management, exploit and utilize rationally and protect ground water resource effectively, investigation and evaluation of ground water resource must be done. MODFLOW model is used to simulate ground water level and water quantity and forecast in this paper. On the basis of results, the exploitation project was constituted. The exploitation amount and distribution should be optimized, the center water level of cone of depression should be effectively controlled while the maximal exploitation amount can be acquired. It provides foundation for the groundwater resources management of the area.
