Abstract: Implementation of the South-to-North Water Diversion Project will exert a profound influence on the ecological environment in water reception areas. According to the theory of ecosystem service function, the eco-environmental benefits attained by the East-Route Phase 1 Project in the reception areas are ex pressed as material and value quantity. By using fuzzy cluster analysis method, the 89 counties and districts in the reception areas are divided into 5 eco-hydrological regions according to their eco-hydrological characteristics. The material and value quantity assessment methods of ecological conservation measures, urban green land and wetland ecosystem are proposed, and corresponding values are calculated. It is found that the total eco-environmental benefit is 6.233 billion yuan, among which the value quantity of ecological conservation measures, urban green land and wetland ecosystem is 0.041 billion yuan, 3.767 billion yuan and 2.425 billion yuan respectively. The results provide the basis for formulating the strategies and measures of eco-environmental protection and water resources management of the Project.
