摘　　要：以新疆干旱区玛纳斯河流域莫索湾灌区150团为例,以2005年为基准年进行模型相关参数率定,以现状年2010年实测地下水数据进行模型验证,以2020年为规划年进行地下水预测,利用具有物理基础的分布式水文模型MIKE SHE模型模拟自然-人工复合水循环过程,并对比现状年与规划年节水灌溉情况及地下水模拟结果。结果表明,由节水灌溉比例的增加引起的地下水位下降值为0.021m,对地下水位下降变化的贡献比例为24.7%。Taking the 150 Regiment of Mosuowan Irrigation District in the Manas Watershed of Xinjiangarid area as an example,the natural-artificial composite water cycle model was established using the MIKE SHE model,which was a distributed hydrological model with physical basis.The data in the base year 2005 were used for model parameters calibration,and the measured data of groundwater level in 2010 were used for model validation,and the groundwater level in the planning year 2020 would predicted.Making a comparison between the situation of water-saving irrigation and groundwater simulation results by the current year and the planning year,the decreased value of groundwater level was 0.021 meters which was resulted by the increasing of water-saving irrigation,and the contribution ratio was 24.7%.
