摘要

The general situation of West Route of South-to-North water transfer project is briefly introduced, and the advance of study on ecological water requirements is simply reviewed. Based on the particular condition of Yalong River Basin, on the principle of analyzing ecological flow, several methods are chosen and used to calculate the ecological flow at the damsite Reba, and then the available quantity of transferable water is estimated. The results show that the ecological flow is 36.3~46.8m3/s, and the available quantity of transferable water is 42.30×108~45.62×108m3 accounting for 69.6%~75.1% of normal annual runoff.
