摘要
针对河流的生态效应、经济可行性和综合利用3方面效应,构建了基于网络分析法(ANP)的河流生态修复后评估指标体系模型。采用最优置信区间理论对其进行改进,以提升专家咨询的准确性,并与传统的河流生态修复后评估模型——层次分析法(AHP)进行比对。结果表明:在河流生态修复后评估这一科学决策上,基于ANP建立的评估模型更加全面且客观,是较AHP更为准确的模型;引入物元可拓法(MEE)将该评估模型应用到某生态防洪堤生态修复工程4个典型年份的综合评估中,其生态修复工程的作用明显,河流生态系统得到较大改善并具有良好的自我维持能力。
Aimed at the three effects of ecology, economic feasibility and comprehensive utilization of riv- er, the paper constructed an index system model of assessment after river ecological restoration based on analytic network process （ANP）. It used the best confidence interval theory to improve the model so as to elevate the accuracy of expert advice, and compared the model with the traditional evaluation model after river ecosystem restoration - Analytic Hierarchy Process （AHP）. The results show that on the scientific decision - making of assessment after river ecosystem restoration, the model built on ANP is more compre- hensive and objective, and is more accurate than the AHP model. It introduced matter - element exten- sion method （MEE） to apply the evaluation model to the comprehensive evaluation of a typical ecological flood ecological restoration project in four typical years. The results indicated that the role of the ecological restoration project is obvious and the river ecosystem has been greatly improved and has good self - sus- tainability
