Abstract: he authors investigated the impact factors on ecosystem environment of hydroelectric exploitation, identified and screened out 13 factors and, according to the degree of eco-environmental impacts, accounted the value loss of all the impact factors of Nuo Zhadu hydroelectric station, Lancang River using market value method, productivity loss method and shadow price method etc. The results were then amended. It is shown that the annual environmental resource loss is 18.84×10~8 yuan RMB, or present value of 175.89×10~8 yuan RMB at the price of 2001. Based on this, the authors analyzed the feasibility of the construction project and the eco-environmental resource compensation measures, and proposed to involve eco-environmental resources into electrovalence cost and its amount and to carry out compensation to cropland occupation during hydroelectric exploitation.
