摘　　要：为了研究塔里木河下游下段地下水位对生态输水的响应,以下游下段阿拉干及依干不及麻剖面为例,运用定性和定量的方法,对近20 a年以来典型剖面地下水位的时空变化进行分析。结果显示:实施生态输水后,地下水位呈明显抬升趋势(其趋势系数为0.1887),抬升幅度具有时空差异性。在时间上,对于地下水位最低的年份,阿拉干(H2井)及依干不及麻(I2井)都在2010年,水位分别为-8.46 m、-7.69 m;对于地下水位最高的年份,H2井在2018年,I2井在2014年,水位分别为-4.35 m、-1.89 m,主要跟当年输水的量及持续的时间有关。在空间上,离水源较远的依干不及麻剖面地下水位相比于离水源较近的阿拉剖面地下水位抬升得好,主要跟剖面的地形地貌、土壤组成物质等有关。2003年—2020年生态输水量与地下水位呈正相关(R^(2)=0.57),并且水位趋于稳定的状态。In order to study the response of groundwater level to ecological water transport in the lower reaches of Tarim River,the Al-agan and Yiganbujima profiles in the lower reaches of the river were taken as examples,and the temporal and spatial changes of groundwater level in typical sections were analyzed by using qualitative and quantitative methods.The results showed that the groundwater level showed an obvious rising trend with the trend coefficient of 0.1887 after the implementation of ecological water transport,and the rising range had spatial and temporal differences.In terms of time,Arakan(H2 well)and Yiganbujima(12 well)both had the lowest groundwater level of-8.46 m and-7.69 m in 2010,respectively,but had the highest groundwater level of-4.35 m in 2018 and-1.89 m in 2014,respectively,which was mainly related to the amount and duration of water transport in that year.In terms of space,the groundwater level far from the water source of Yiganbujima section was better than that of Alagan section which was closer to the water source,mainly related to the topography and soil composition of the profile.There was a positive corre-lation between the ecological water transport and the groundwater level from 2003 to 2020(R^(2)=0.57),and the water level tended to bestable.
