Abstract：Combined with the ecological water-transporting project being carried out in the lower reaches of Tarim River,based on the data of runoff and groundwater level,the paper analyzed the change of water regime suffered from man-made disturbance in the main course of Tarim River.The results showed that due to an amount of water diversion for agriculture in the head stream,the the net water input into the main course（decreased） by 0.2×108m3/a from 1950s to 1990s,but since the mid-1990s it has exhibited a slight increasing trend.Runoff of Yingbaza still kept decreasing before and after year 2000.However,that of Kala behaved wide-range increase from spring to early winter after water transporting.The peak flow was nearly 2 times that of before and occurred late in time.Meanwhile,the groundwater level of 9 sections changed largely in the lower reaches after water transporting.In longitudinal direction from Daxihaizi to Taitema Lake,the lifting extent showed step-decreasing trend,while in lateral direction,the groundwater level of every well presented band-lifting trend with the times of water transporting increased.The farther away from river way,the less the fluctuation is.The response scope after five times' water transporting had reached to 1?200?m.To a certain extent,the active disturbance of water transporting in the lower reaches relaxed the negative influence by the disturbance in head stream and upper reaches.The ecological benefit brought by water transporting is positive.
