摘要
引入物元可拓法对防护林项目综合效益的评价进行研究,构建防护林项目综合效益物元可拓评判模型。利用物元分析法,将防护林项目综合效益的等级、评价指标及其特征值作为物元,确定防护林项目综合效益的经典域、节域及待判物元,应用物元和可拓集合中的关联函数建立了防护林项目综合效益物元评判模型;通过计算指标权重及关联度,将多指标的评价归结为单目标决策,给出定量的数值评定结果,直观全面地衡量了防护林项目综合效益水平。
The extension multi-factor evaluation method is utilized to assess the comprehensive benefits of ecological forestry project.On the basis of matter element analysis theory,the grade,evaluation indicators,and characteristic values of comprehensive benefit are taken as matter elements and then the sutra field,controlled field,and matter element for judge are determined.A matter element judge model for comprehensive benefits of ecological forestry project is established using correlation function of extension set and matter element.The multi-ingredient of comprehensive benefits evaluation is transformed into the single-object decision by the calculation of indicators weight and their correlation,quantitative numerical evaluation result is obtained,and the results can directly show the integrative level of the ecological forestry project.
