摘　　要：为准确反映塔里木河下游生态输水工程后地下水的动态变化,实现为本地区开展大规模的生态恢复和重建工作提供科学依据,在塔里木河下游沿321km河道上布设了9个监测断面和39口监测井,采用电导法定期监测地下水位近3年。结果显示:输水后地下水位在河道纵向、横向上有各自的变化规律,说明生态输水的效益是逐步显现的。因此,对本地区生态输水的综合评价应该放在几年以后再开展。同时,通过对生态输水后地下水位变化的分析,提出了调整输水规模和方式的建议。In order to show objectively the dynamic change characteristic after ecological water transporting project, and realize the goal to provide the scientific evidence for extensive restoration and reconstruction in the lower reaches of Tarim River, nine monitoring sections and thirty-nine monitoring wells are built along the 321km river way to monitor the variation of groundwater level. After nearly three years' monitoring and analyzing in this region, it is found that the groundwater levels have different change characteristic in lengthways and transverse direction respectively. These results indicate that the benefits of ecological water transport will be present gradually. Therefore, the assessment of ecological water transporting project on environment should be done in the future several years. In addition, on the basis of the analysis on groundwater level after water transport, the suggestions on adjusting the way and scale of ecological water transport are presented.
