Abstract
The transfer project from Yangtze River to Hanjiang River, as a matching project of the South-to-North Water Transfer will make a great effect on the eco-environment of the middle and lower reaches of Hanjiang River. The paper analyzes its effect on the ecosystem environment from the aspects of level, flow, growth of fish,algae based on the quality model and the RQEM. The results show that after the transfer project, level and the capacity of the middle and lower reaches of Hanjiang River will be enhanced, the concentration of the pollutant (COD) will be reduced, the water bloom phenomenon will be controlled, fish's survival space will be improved, but the potential risk of schistosomiasis diffuseness may be increased.
