在模糊物元分析原理的基础上，采用基于欧式贴近度的模糊物元模型评价生态林项目综合效益水平。根据生态林项目综合效益评价特点，提出综合效益评价指标体系，确定评价等级与单因素评价标准；将生态林项目综合效益的各个评价等级及待评价项目作为物元的事物，将各评价等级和待评价项目的评价指标及其模糊量值作为复合模糊物元，通过计算复合模糊物元与标准物元之间的欧式贴近度，分析待评价生态林项目综合效益水平。以昕水河流域生态防护林项目为例，计算表明该生态林项目综合效益处于良-中等级之间，其结果直观地衡量了该项目综合效益水平。

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.
