摘要
探讨不同的回灌及回灌后开采方式对地下水位的影响,将有助于对水资源的时空再调度并达到高效开发利用水资源。以新疆温宿县台兰河流域地下水库为例,在分析水文地质条件基础上构建了地下水流场数值模型,确定了回灌井及开采井、观测井的位置及回灌、回灌后开采方案,分析了HG1、HG2回灌井各自在全年回灌、汛期回灌时的地下水位变化情况,指出汛期回灌效果最佳;通过比较无回灌、开采无回灌、开采回灌、回灌无开采四种情况下地下水位变化情况,指出回灌后开采对区域地下水位影响显著,从而确定出HG1为最佳回灌井位。研究结果表明,摸清回灌及回灌后开采地下水的运动规律,将有利于台兰河流域地下水资源的优化调度。
Different recharging and pumping plan has impact on underground water level,which will be conducive to manage water resources in time and space and achieve the aim of high efficient utilization of water resources.Taking the groundwater reservoir of Tailan basin in Wensu County,Xinjiang Province for an example,numerical model of groundwater flow field is established based on the analysis of hydrogeologic condition.The location of recharge wells,pumping wells and the observation wells and the plan of recharge and pumping are determined.The change of underground water level is analyzed under the conditions of the yearly recharge and flood period recharge with recharge wells HG1 and HG2.It points out that recharge in flood season is the best plan.Comparison of underground water level change in four cases as exploit without recharge,exploit with recharge,no exploit and without recharging,recharge without exploit,it finds out that mining after recharge has significant impact on regional underground water level and it determines that HG1 is the best recharge wells.The results show that study of change regulation of underground water under pumping and recharge will be conducive to optimal scheduling of groundwater resources in Tailanhe basin.
