Study On Impact Post-evaluation Index System And Method Of Water Conservancy Construction Project

The impact post-evaluation for water conservancy construction projects is the most important for summarizing the experiences and lessons, improving the scientific level of the decision. For impact post-evaluation for water conservancy construction projects involving of many fields in a large range, and many evaluation indexes are difficult to quantify, the researches of impact post-evaluations for water conservancy construction projects are short of depth and methods, and are mainly qualitative.To perfect the evaluation index systems and the methods of impact post-evaluation for water conservancy construction projects, impact post-evaluation for water conservancy construction projects is taken as the research object and researched in three aspects:technology influence, society influence and environment influence.1) According to the characteristics of impact post-evaluation for water conservancy construction projects, directed by the principles for evaluation indexes system construction, evaluation indexes are drafted and screened, and impact post-evaluation for water conservancy construction projects is constructed, and indexes are quantified.2) Evaluation models based on Variable fuzzy sets are researched, combining water conservancy project's own characteristics, impact post-evaluation model for water conservancy construction projects based on variable fuzzy sets are constructed.3) Inundation influence processing project in Linhuaigang, Henan province is taken as the case, combining the characteristics of the case and data collected, the evaluation indexes system and models constructed here are applied to execute impact post-evaluation, so as to verify the feasibility and rationality of the method.
