Abstract: Based on fuzzy matter-element analysis theory, a model which combines fuzzy matter-element analysis and Euclid approach degree, is established to evaluate comprehensive benefits of ecological forestry project. Depending on the characteristics of comprehensive benefits evaluation, the evaluation index system is put forward, and the evaluation grades are determined as well as the evaluation standards of the indices. Then, regarding the different evaluation level of the comprehensive benefits and the evaluated project as the object of matter-element and constructing the compound fuzzy matter-element through various evaluation indexes and corresponding fuzzy values, the evaluation result is achieved by calculating Euclid approach degree between the fuzzy matter-element and the standard fuzzy matter-element. With the ecological forestry project in Xinshuihe watershed as an example, it indicates that the comprehensive benefit level of the project is between good and middle, and the results directly show the integrative level of the ecological forestry project.
