塔里木河下游生态输水对地下水补给量影响的研究

Study on the Impact to the Groundwater Recharge by Ecological Water Conveyance in Lower Reaches of Tarim River

文章依据塔里木河下游段现有的2000—2020年的地下水监测数据,对生态输水地下水前后水面线方程进行拟合,并在水均衡原理的基础上,对经过了21次生态输水之后的塔里木河下游段地下水埋深时空变化特征进行分析,以此对地下水的补给量进行估算,以更好支持后续的生态输水。

The ecological water conveyance groundwater front and rear water surface profile equations are matched according to the existing groundwater monitoring data in lower reaches of Tarim river section in 2000-2020 in the paper.The spatial and temporal variation characteristics of groundwater depth in lower reaches of Tarim River after 21 times of ecological water conveyance are analyzed on the basis of the water balance principle,the groundwater recharge is estimated accordingly,thereby better supporting subsequent ecological water conveyance.
