After the implication of ecological water transfers in Lower Tarim River since 2000, the riparian vegetation in Lower Tarim River is restored. Based on the NDVI of MODIS remote sensing data, the vegetation dynamic at Yingsu in Tarim River from 2000to 2012is analyzed. With the help of the advantage of high spatial resolution of NDVI data, 6contiguous points within the distance of 1500m away from the bank are selected to investigate. The data field of pixel reliability in the data set is employed to screen the valid data from 296images of 2000-2012. The analysis of the NDVI series suggests that, the NDVI of 4point, i.e. C3, C5, C6and C7, within 1000m away from the bank, present notable increasing trend, and the average NDVI increasing rate of C3is 5.34×10-6/day. In the direction away from the bank, annual NDVI from C3to C7decrease gradually. The average relative increase rate of annual NDVI of C3, C5, C6and C7are in the range of 3.33%~1.36%. At C8and C9, which are 1150m and 1500m away from the bank respectively, the NDVI don''t have obvious change. The spatial extent near the river where the ecological water transfers have a restoration effect on the riparian vegetation is limited and the extent where the riparian vegetation is notablely restored by the ecological water transfers is within about 1000m away from the river bank.
