摘  要：
针对传统层次分析法(AHP)较易受人为主观因素影响的缺陷,采用OWA算子削弱主观极值偏差对权重准确性的影响,修正传统AHP的部分缺陷;并运用TOPSIS量化样本与标准之间的相对关系,最终构建OWA-AHP-TOPSIS耦合模型。将该模型应用于大沽河流域,选取总硬度、Cl~-、TDS、CO■、NO~-_3、NO~-_2、NH~+_4 7个指标作为评价因子,对流域内12处水样点进行地下水水质评价。结果表明,所选水样中Ⅲ类水占41.7%,Ⅳ类水占58.3%,水质污染情况总体较为严重,区域内南北部尤为恶劣,这与当地居民不合理的生活污水排放、低效率的农业化肥利用等有关,应就此开展相应整治。同时将OWA-AHP-TOPSIS耦合模型与AHP-TOPSIS法、单因子指数法和内梅罗指数法的水质评价结果进行对比,发现耦合模型在污染严重区域能取得更为客观的评价结果,具有更优的适用性。

摘  要：
Aiming at the defect of traditional analytic hierarchy process(AHP) which was easily affected by subjective factors, OWA operator was adopted to reduce the influence of subjective extreme value deviation on the accuracy of weight and correct some defects of traditional AHP. Finally, the OWA-AHP-TOPSIS coupling model was constructed by using TOPSIS to quantify the relative relationship between samples and standards. The model was applied to Dagu River Basin, with 7 indexes of total hardness, Cl~-,TDS, SO_4~(2-), NO~-_3, NO~-_2 and NH~+_4 were selected as evaluation factors to evaluate groundwater quality of 12 water sample points in the basin. The results showed that 41.7% of the selected water samples were classified as class Ⅲ water and 58.3% as class Ⅳ water. The water quality pollution was generally serious, especially in the north and south of the region, which was related to unreasonable domestic sewage discharge of local residents, low efficiency of agricultural fertilizer utilization and so on. Therefore, corresponding remediation should be carried out. Meanwhile, it was found that the coupling model could obtain more objective evaluation results in the areas with serious pollution with better applicability through comparing OWA-AHP-TOPSIS coupling model with AHP-TOPSIS method, single factor index method and Nemero index method in water quality evaluation results.
