摘　　要：塔里木河下游大西海子水库以下河段自1972年至2000年发生的持续断流是绿色走廊生态劣变的主要原因。从2000年5月至2011年11月,塔里木河下游共进行了10次生态输水。本文利用输水期间的地下水监测资料,运用水均衡法对大西海子以下河段历次输水过程中的水量转化进行了计算,量化了河道水量的转化项与塔里木河下游地下水的恢复程度,揭示了塔里木河下游河道径流-补给转化-蒸腾耗散的水文过程,文中结论可为今后进一步优化输水方案、合理配置区域水资源以及植被的有序恢复提供科学依据。The ecological degradation in the green corridor was mainly caused by continuous river blanking in the lower reaches of Tarim River below the Daxihaizi Reservoir from 1972 to 2000. From May of 2000 to November of 2011, 10 times ecological water transition had played an important role in raising groundwater table in the lower reaches. By use of measured data of groundwater during the period of water transition, the paper established water balance equations and made the calculation of water volume below Daxihaizi Reservoir on every water releases. Then, the various water volume transform from river flow were calculated and the level of groundwater restoration were evaluated. Meanwhile, it revealed the hydrological processes that is from channel runoff to recharge ＆ transform and transpiration ＆ dissipation in lower reaches of Tarim River . The results provide scientific basis for the optimum of water release scheme, reasonable allocation of water resources and vegetation restoration.
