摘要

Two factors of the vegetation coverage and its types sensible to the ecological changes before and after the Emergent Water Transportation Project are investigated and analyzed in a qualitative and quantitative way based on the TM in 1999, ETM~+ in 2002, ASTER in 2004 and the background data of the lower reaches of Tarim River. The research indicates that: (1) The moderate and satisfactory coverage of vegetation evidently go up in area by 1.68×10~3 hm~2, 9.09 ×10~3 hm~2 respectively. The poor, lower vegetation coverage areas constantly fall into decline by 7.83 ×10~3 hm~2, 9.99 ×10~3 hm~2 on the average from 1999 to 2004 respectively, and some turn for worse is prevented and stopped in some area. (2) The farm land increases from 1.48×10~4 hm~2 in area in 1999 to 1.51×10~4 hm~2 in area in 2002, and then to 1.72×10~4 hm~2 in area in 2004 with a yearly increasing ratio of 3.52%. (3) To be concluded, the emergent water supply plays an important role in promoting the ecological environment in the research region. But there is a long way to rejuvenate the whole Green Corridor and turn the extremely fragile ecological environment as a whole on a large scale.
