摘　　要：济源得名于济水发源地,老龙潭泉作为济水西源之一,于2015年断流,为了使古泉复流,济源市启动了一系列项目。本文基于国际通用的地下水模拟软件Visual MODFLOW,为了实现老龙潭泉复流,在全面整理及分析济源盆地水文地质资料的基础上,提出了7个泉水复流方案,包括3个单一措施复流方案及4个综合措施复流方案,并预测出了7个方案下老龙潭泉水位动态变化。通过对比分析,发现单一措施复流方案下实现泉水复流难度较大,所以采用两种或三种复流措施相结合的综合复流方案,结果表明老龙潭泉最佳复流方案为关闭青多水源地、关闭工业自备井及减少龙泉湖泄流量相结合的综合复流方案,在该方案下,老龙潭泉的复流是有保障的。Jiyuan is named after the birthplace of Jishui,Lao longtan spring,as one of the west sources of Jishui,was cut off in 2015,In order to make the ancient spring flow again,Jiyuan launched a series of projects. Based on the international groundwater simulation software Visual MODFLOW and the comprehensive analysis of hydrogeological data in Jiyuan basin,in order to realize the reflow of Laolongtan spring,this paper proposed 7 reflow schemes,including 3 single-measure reflow schemes and 4 comprehensive measure reflow schemes,and predicted the dynamic change of Laolongtan spring water level under 7 schemes. Through analysis and comparison,it is found that it is difficult to realize the reflow of spring water in a short time under the single-measure reflow scheme,so the comprehensive reflow scheme combining two reflow measures is adopted. The results show that the best reflow scheme of Laolongtan spring is the comprehensive reflow scheme combining the lifting of Longquan lake level,closing the water source of Qingduo and closing the industrial-owned Wells,under this scheme,the reflow of Laolongtan spring is guaranteed.
