【摘要】：黄藏寺水利枢纽工程建成运行后,将在输水关键期采用大流量输水并废除部分平原水库或其灌溉功能,地下水补给的减少或将对黑河中游张掖盆地地下水环境产生影响。由于黑河中游张掖盆地地表水与地下水存在密切联系,单独采用地下水数值模型难以准确描述地表水与地下水的转化关系,因此采用MIKE-SHE软件建立了黑河中游盆地的地表水—地下水耦合数值模型,通过校正后的模型对工程运行后的地下水演变进行了预测。模拟结果表明:黄藏寺水利枢纽工程运行对黑河中游张掖盆地地下水影响有限,河道与水库渗漏减小引起的地下水位下降值远小于当地地下水位天然变幅,可由地下水系统自然调节。
[Abstract]:Huangzangsi water conservancy project after the operation, in the critical period of water with large flow water and the abolition of part of the plain reservoir or its irrigation, groundwater recharge will reduce or on the middle reaches of Heihe Zhangye basin groundwater environmental impact. Because of Heihe in the middle reaches of Zhangye basin, the surface water and groundwater are closely connected, separately using the groundwater numerical model it is difficult to accurately describe the conversion between surface water and groundwater, thus established between surface water and groundwater in the middle reaches of Heihe basin coupled numerical model by using MIKE-SHE software, through the corrected model of engineering operation after the groundwater evolution were predicted. The simulation results show that the huangzangsi water conservancy project to run a limited impact on groundwater in the middle reaches of Heihe basin in Zhangye River and reservoir leakage, reduce underground water level caused a decrease of the value of the underground water level is far less than the local natural amplitude can be It is naturally regulated by the groundwater system.
