根据塔里木河下游断流区域含水层水文地质特征及其实际输水过程中河水对浅层地下水的补给规律 ,建立了塔里木河下游绿色走廊生态输水河道附近区域地下水运动的一维非稳定流模型 ,并通过在整个输水过程中流量与水位两种边界条件相互转换的一种方法求解模型。最后应用上述模型分析了间歇性输水条件下塔里木河下游断流河段河道两侧地下水位恢复状况 ,为输水生态效益的定量评价及其今后输水工作的决策提供理论基础。
According to the hydrogeological characteristics of the aquifer in the cutoff area of the lower reaches of the Tarim River and the recharge rules of shallow groundwater during the actual water conveyance, a one-dimensional unsteady flow model of groundwater movement in the ecological corridor near the Tarim River was established. , And solved the model through a method of mutual conversion between the two boundary conditions of flow and water level in the entire water conveyance. Finally, the above model was applied to analyze the recovery of groundwater table on both sides of the river in the lower reaches of the Tarim River under intermittent water conveyance, providing a theoretical basis for the quantitative evaluation of the ecological benefits of water conveyance and its future decision on water conveyance.
