摘要
采用MODFLOW软件,建立引黄入冀补淀工程地下水流数值模型,预测了不同输水情景下输水沿线、典型受水区的水量、水位变化,并分析了盐渍化影响。结果表明:不同方案对工程两侧地下水均有积极补给作用,年补给量为1.29亿~1.98亿m^3,地下水位最大抬升4.00 m,单侧影响距离为3.00~3.30 km。工程建成运行后,将对沿线及受水区地下水产生积极影响,一定程度上改善沿线及受水区的生态环境。
This study used MODFLOW software to establish groundwater flow mathematical and numerical models of the Yellow River-toBaiyangdian Water Transfer Project and predicted the change of water quantity and level along the line and typical intake area under different water conveyance situations and analyzed the impact of salinization. The results show that different schemes have positive supply to both sides of the groundwater,and annual recharge is within 0.129-0.198 billion m^3,and the maximum lifting height of groundwater level is 4.00 m and unilateral impact distance is within 3.00-3.30 km. After putting into operation,the project will have a positive impact on groundwater of intake area and along the line,and improve ecological environment of intake area and along the line.
