A COMPREHENSIVE METHOD FOR EVALUATING THE IMPACT OF LARGE HYDROELECTRIC PROJECTS ON ENVIRONMENT AND ECOLOGY
大型水电工程对环境与生态影响的综合评价方法

According to system engineering principle, an index system for comprehensive evaluation of the impact of large hydroelectric projects on environment and ecology was suggested. Based on the system, a classification procedure and relevant standards for evaluating the degree of the influence on environment were proposed and a weighted multi-level linear model and a fuzzy comprehensive judgement mathematical model were also introduced. The methods were applied to evaluate the environmental impact of the project at the Three Gorges.
