Abstract: Classifying the influencing factor of benefit evaluation of water transfer project based on cost analysis and benefit analysis. The benefit evaluation index system of east line of South-to-North water transfer project is established, including six aspects of Economic cost, Social cost, Environmental cost, Economic benefit, Social benefit, Ecological benefit, totaling 16 indexes. At the same time, the standards of each index corresponding to different grades are determined. In view of the single result in the process of benefit evaluation, ignoring the randomness and fuzziness of index data, a comprehensive evaluation method based on combination weight and trapezoid cloud model is adopted. In this method, the weight obtained by combination of G1 and improved CRITIC weight method is combined with the index certainty obtained by trapezoid cloud model to realize the comprehensive evaluation of project benefits. Finally, taking Jiangsu section of phase I of east line of South-to-North water transfer project as an example, the effectiveness and applicability of the proposed benefit evaluation system and method are verified by analyzing and comparing the evaluation results.
