摘　　要：为对比加权欧氏距离法及模糊综合评价法在阳泉市7条主要河流水质评价中的优劣性,以2019年1月河流水质监测结果为依据,采用加权欧氏距离法和模糊综合评价法综合评价阳泉市地表水体环境质量。对比分析表明,模糊综合评价法采用评价标准的依据,会造成最终评价结果无法有效反映水体的实际状况;加权欧氏距离法在给出评价断面水质级别的同时,反映评价断面对于某一水质标准的贴近度及水质的变化趋势,评价结果显示的信息更加真实多元,在水质评价中的表现更加优良,可在水环境治理中更好地发挥作用。In order to compare the advantages and disadvantages of the weighted Euclidean distance method and the fuzzy comprehensive evaluation method in the water quality evaluation of seven main rivers in Yangquan City,based on the river water quality monitoring results in January 2019,the weighted Euclidean distance method and the fuzzy comprehensive evaluation method are used to comprehensively evaluate the surface water environment quality of Yangquan City.The comparative analysis shows that the fuzzy comprehensive evaluation method can not effectively reflect the actual situation of the water body if it uses the basis of the evaluation standard;The weighted Euclidean distance method can not only give the water quality level of the evaluation section,but also reflect the proximity of the evaluation section to a water quality standard and the change trend of the water quality,and the information displayed by the evaluation result is more real and diverse,which has better performance in water quality assessment and can play a better role in water environment treatment.
