摘　　要：黄水沟调水工程改变博斯腾湖水动力条件,引起湖区及下游水体矿化度改变。为探讨工程影响极其适宜的运行方式,采用MIKE21软件构建水动力水质二维数值模型并设计不同情景方案。模拟结果显示:工程运行可降低全湖矿化度并改善矿化度空间分布不均,当调水量为3亿m~3/a时效果最优,全湖年均矿化度可降低86 mg/L,缓解博斯腾湖咸化风险。工程运行导致矿化度从博斯腾湖转移至下游孔雀河,出水矿化度由912 mg/L增至940 mg/L,浓度变化对下游灌区作物影响有限。The Huangshuigou Water Transfer Project has changed the hydrodynamic conditions of Bosten Lake,which causes a different mineralization in Bostan Lake and downstream.To explore the influence and the optimal operation mode of the project,this paper applies MIKE21 software to establish a two-dimensional hydrodynamic water quality model.Duo to the simulation results of five scenarios,the Huangshuigou Water Transfer Project can lower the level of mineralization and the uneven spatial distribution in Bosten Lake.The annual mineralization in Bosten Lake would reduce by 86 mg/L by diverting 3×108 m3/a runoff from Kaidu River to Huangshuigou River,which also leads to the mineralization relocating from Bosten Lake to downstream.Fortunately,the outflow mineralization degree has changed from 912 mg/L to 940 mg/L,which means a small risk to the irrigated area downstream.
