Ecological Benefit Assessment of Water Transfer Project from Niulan River to Dianchi Lake
Yunnan Water Transfer Project from Niulan River to Dianchi Lake is one of the 172 major water conservancy projects for water-saving and water supply under the State Council,and is also one of the key measures for comprehensive water pollution control in Dianchi Lake.Since the operation of this project for over 9 years,a total of 46.06×108m3 of water has been transferred to Kunming,including 42.15×108m3 of supplementary water to Dianchi Lake and 3.91×108m3 of urban emergency water supply,which has played a huge ecological benefit.To reasonably evaluate the ecological benefits generated by the project,this paper evaluates the ecological benefits of the project from both qualitative analysis and quantitative calculation.Three methods,namely ecological compensation method,equivalent substitution method,and ecological water pricing method,are used in quantitative analysis to quantify ecological benefits into value for money.After comprehensive analysis,it is recommended to use the equivalent substitution method to calculate the ecological benefits of the project.
