摘要
To reduce water conservancy projects' negative effects on the ecological environment, in this paper, a method is proposed to assess the impact of hydropower stations on the environment in the processes of the flood discharge and energy dissipation. It utilizes the hesitant fuzzy linguistic information to describe the problem's uncertainty and fuzziness, portrays decision maker's satisfaction degree with the increasing marginal utility, and applies the hyperplane to establish a mathematical programming model. Then, the undetermined parameter in the model is discussed, and a decision-making procedure for solving the considered problem is provided. Furthermore, an experiment is designed to verify the availability and reasonability of the proposed method by comparing it with an existing one. Finally, the method is applied to assess the impact of giant hydropower stations' flood discharge and energy dissipation on the environment in Sichuan, China.
