Due to human irrational resource exploit, many environment problems have become more and more serious at the lower reaches of Tarim River, which made this region become one of the most typical areas of environment degradation in western areas of China. In this paper, according to the monitoring and analysis in this region, and dynamic change of some environmental factors after five times ecological translating water in recent three years, the active effect of translating water on the ecological environment was analyzed. The results are as follows- (1) the ground-water level has changed obviously after translating water, and has different spatio-temporal rule. In time, the nearer well is more sensitive to translating water than the distant well. In space, there are different uplift of water level in different distance from river or different part of river. (2) the effect of natural vegetation on translating water are mainly represent in the coverage and special number increased. (3) Due to the respond range is still very smaller than the total range, the project of translating water should go on at the lower reaches of Tarim River. At the same time, it is necessary to adjust the ways and size of translating water for improving this regional ecological restoration.
