基于生态足迹法的坝型选择

:Hydropower project brings about economic and social benefit in flood control,water supply,irrigation and so on，changes the environment, and brings negative influence to ecological environment.For sustainable development, Ecological footprint model which is a new assessment device to quantitatively estimate a region’s sustainability,is applied to hydropower project.The paper explains the ecological footprint of hydropower project,makes the ecological footprint model of hydropower project. Then the ecological footprint of the different dams in the feasibility study report of a hydropower project is computed and anslyzed. The conclusion is that the material ecological footprint is the most in all.At last,we could take the best type of dam on ecological footprint.
