Abstract: In recent years, the exploration of water and soil resources in the Tarim River Basin has led to increasingly violent contradiction between water supply and demand, especially in dry years. Ecological and social securities are seriously threatened. It is urgent to put forward scientific and reasonable ecological water transfer mode and ecological compensation scheme. Using surface runoff, water diversion and recession and groundwater depth of the four source streams and main stream of the Tarim River Basin, remote sensing data of the main stream and meteorological data, this paper calculated the water loss of each river and ecological water demand in the lower reaches of the main stream based on water balance principle, and water resources allocation scheme in dry years was put forward. Furthermore, the ecological water transfer mode in dry years and corresponding ecological compensation scheme were determined. The results showed that in dry years water demand in the lower reaches is 7.01×108 m3, taking at least 10.70×108 m3 of water in the upper reaches. If transferring water from the source stream in the upper reaches to the source stream in the lower reaches, the total benefit and economic benefit of 1 m3 water will be reduced by 38.2% and 81.2%, respectively. Therefore, the transferring water from the upper reaches to the lower reaches is impracticable. After water transfer, the source stream in the upper reaches should compensate the Kaidu-Kongque River 3.4 yuan/m3. This study provides a scientific basis for the development, utilization and management of water resources.

Key words: dry years, ecological compensation, ecological water transfer, the Tarim River Basin
