Abstract:
The establishment of ecological compensation mechanism in the water source area is one of the most important contents for the paid utilization system of water resources, and the measurement and calculation of ecological compensation are an important guarantee for the paid utilization system. In this study, the central water source area in the Middle Route of South-to-North Water Diversion Project was selected. The methods such as the ecological service function value, static accumulation, and indirect calculation were used to determine the ecological compensation in this area from the aspects of direct cost of ecological protection construction and indirect cost of development opportunity loss. The results showed that 0.44 billion yuan per year should be compensated according to the direct cost of ecological protection construction and water environment treatment, and a total of 0.28 billion yuan should be compensated according to the indirect cost of development opportunity loss. On the basis, the development stage coefficient and the distribution rate were introduced to compute the distribution weight coefficient of the water intake area. It was determined that Henan Province Hebei Province, Beijing, and Tianjin should pay 0.13, 0.13, 0.05, and 0.029 billion yuan to Shiyan City for the usage of water resources in 2011, respectively.
