Research and Progress on Analysis of Eco-Environment Affected by Hydropower Projects
The contents of analyzing and evaluating impacts of hydropower projects include natural environment,ecological environment and social environment. And the methods include RVA/ IHA method,analytic hierarchy process,fuzzy comprehensive evaluation method,cost benefit analysis method and fuzzy matter - element comprehensive evaluation method et al. After comparing those methods,this paper found out some disadvantages,for example,the requirements of data were much higher for analytic hierarchy process and fuzzy comprehensive eval-uation method. And it was hard to operate. Besides,because the evaluation results partly depend on subjective opinions,so most of those methods were not totally objective.
