Study on variation of ground-water after ecological water transport in the lower reaches of Tarim River

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.
