【Abstract】 Runoff from mountains of the four source rivers of the Tarim River in 2007 was 238.1×108m3,which is 13.17×108m3 or 5.9% more than the long-term average and belongs to an abundant water year.The air temperature in the maintain area of the river basin was 1.2 ℃ more than the average of the latest 30 years,accordingly the altitude of 0 ℃ layer was 62 gpm higher than the average over 12 years from March to October and precipitation was 15.4% on the high side.According to the request of comprehensive programming of short-term rehabilitating the Tarim River Basin,the water amounts from source-rivers at the Alar station of the Tarim mainstream should reach 46.5×108m3,and the water transportation from the Kaidu Konque River to the mainstream should reach 4.5×108m3,the total sum from the four source-rivers should reach 51.0×108m3,moreover the releasing water to downstream at the Daxihaizi reservoir should be 3.5×108m3 and the water flow should run to the Taitema Lake up to 2005.But,actually,in 2007,the three source-rivers above the Alar station supplied only water amount of 28.57×108m3,which was 17.93×108m3 less than the request and achieved only the task of 61.4%;water supply from Kaidu Konque River was 2.99×108m3,1.51×108m3 short,and achieved only 66.4% of its task;the summed four source-rivers water supply only 31.56×108m3,short of 19.44×108m3 and achieved only 61.9% of the request;the water amount really flowing to downstream at the Daxihaizi reservoir was 0.14×108m3,short of 3.36×108m3 and realized only the task of 4%.In addition,the water flow was quickly stopped,unable to get to the Taitema Lake. The water consumption in the upper mainstream section of the Tarim River is 21.88×108m3,which occupies 69.4% of the annual runoff at the Alar station and is the maximum section of water consumption along the mainstream.The consumption for the middle mainstream section is 6.12 ×108m3,accounting for 19.4%,and that for the downstream is 3.51×108m3,accounting for 11.1%.The water consumption at plains before mountains of the source-rivers and the upper reaches of the Tarim mainstream is increasing,but in the middle section it is decreasing correspondingly,and it is near the average in the lower section.From 2000 to 2007 nine time of water conveying with total water amount of 22.59×108m3 has done to the downstream.更多还原
