摘　　要：玛纳斯河平原区水循环的可持续发展状态在一定程度上由地下水位动态来反映。利用Hydrus-1D和Visual Modflow 4.2建立包气带及含水层水分迁移转变的数值模型,对不同灌溉模式下地下水水量和水位的变化范围及程度进行定量分析。结果表明:该模型的模拟效果较好,在三种灌溉模式下,到2020年和基准年相比地下水水位的最大变化值分别为下降0.23m、上升2.1m、下降0.8m。The sustainable development of water circulation in the plain area of manas river is reflected in the dynamic of underground water level to some extent By using hydrus-1d and Visual Modflow4.2, the numerical model of water migration and transformation of gaseous zone and aquifer was established, and the variation range and degree of groundwater water quantity and water level under different irrigation modes were quantitatively analyzed. Under the three irrigation modes, the maximum change value of groundwater level in 2020 is 0.23 m lower, 2.1 m higher and 0.8 m lower than the base year.
