摘要
岷江(眉山段)流经众多工业城镇,大量污水排入河流,开展对岷江(眉山段)水质安全评估工作,对提高岷江水环境质量具有指导性意义。本文在结合主成分分析法筛选评价指标与确定指标权重的基础上,通过模糊综合评价法(FCE)对岷江流域(眉山段)水质安全进行评价,构建完整的岷江流域(眉山段)水质安全评价体系。结果表明,岷江干流水质安全状况整体较好,眉山采取的水环境综合污染治理措施都有显著的改善效果。
The Meishan Section of Minjiang River flows through many industrial towns and a large amount of sewage is discharged into the river.Carrying out the water quality safety assessment of the Meishan Section of Minjiang River is of guiding significance for improving the water environment quality.Based on the combination of principal component analysis method to screen the evaluation index and determine the index weight,this paper evaluates the water quality safety of the Minjiang River Basin(Meishan Section)through the fuzzy comprehensive evaluation method,and builds a complete water quality safety evaluation system.The results showed that the water quality and safety status of the main stream of the Minjiang River was generally good.The water bodies of the tributaries of the Minjiang River have been polluted to varying degrees.After treatment,the water quality has been continuously improved.The comprehensive water environment pollution treatment measures adopted by Meishan have a significant improvement effect.
