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.

犹豫模糊语言超平面一致性规划法评估水电站环境影响


为了减少水利工程对生态环境的负面影响，本文提出了水电站泄洪和消能过程对环境影响的评估方法。它利用犹豫模糊语言信息来描述问题的不确定性和模糊性，刻画决策者对边际效用递增的满意程度，并应用超平面建立数学规划模型。然后，讨论模型中的未确定参数，并提供解决所考虑问题的决策程序。此外，还设计了一个实验，通过与现有方法进行比较来验证所提出方法的可用性和合理性。最后，应用该方法评估了四川省特大型水电站的泄洪和消能对环境的影响。
