基于模糊层次分析法的大型水利枢纽效益评估

选定20项效益相关指标,基于模糊层次分析法构建大型水利枢纽效益评估模型。以南水北调东线工程江都水利枢纽为例,考虑强调生态环境情景下和正常情景下的江都水利枢纽综合效益情况。研究结果表明:江都水利枢纽经济效益、社会效益、生态环境效益和综合效益的级别特征值都在4.2以上,效益显著。在冲淤保港、提高绿化覆盖率、提高当地知名度、防治自然灾害方面的效益尤为突出。对准则层权重分配进行扰动,综合效益特征值仅相差1.3%,表明准则层权重分配对综合效益评估结果影响较小。

Benefit assessment of large hydro-junction project based on improved FAHP

The paper selected 20 benefit indicators relating to economy, society, and ecology. It used improved FAHP to build a comprehensive evaluation model for large hydro-junction project. Taking Jiangdu hydro-junction for example,it thought the comprehensive benefit situation of Jiangdu hydro-junction project under the scenarios of ecological environment and normal situation.The results show that Jiangdu hydro-junction has notable benefit,all of the level eigenvalues of economy, society and ecology environment benefits are above 4.2 The benefits in protecting port,improving green coverage,increasing local visibility and preventing natural disaster are espically outstanding.The eigenvalues of comprehensive benefit only only changes by 1.3% through disterbing perturbing layer weight distribution,which indicated that the weight distribution of rule layer has little effect on the assessment results of comprehensive efficiency.
