摘要
为了提高昆山市老城区水环境质量、改善河道生态景观效果,昆山市于2012年起对老城区内多条河道进行了综合整治。由于影响河道水质的因素众多,为了能够较为客观地评价治理前后的水质改善情况,通过主成分分析法及建立模糊综合评价模型,对治理前后水质进行综合评价。结果表明,治理后Ⅲ至Ⅳ类水的隶属度有所提高,Ⅴ类水的隶属度有所降低,西仓基河、后街河的水质指标有较大幅度提高。经过综合整治,昆山市老城区河道水环境质量有所提高,与实际治理情况相符,可见所提方法可行、有效。
In order to improve the water environmental quality and the river ecological landscape in old urban area,river regulation of Kunshan City was carried out in 2012.There are many factors that affect water quality,in order to be more objective to evaluate the improvement,do comprehensive evaluation of the river water quality in old urban area of Kunshan by the principal components analysis and fuzzy comprehensive evaluation model.The results show that after regulation,the membership degree ofⅢto Ⅳ water has increased,the membership degree ofⅤ water has decreased,the water quality index of Xicangji River and Houjie River improve significantly.After a comprehensive regulation of the old urban area of Kunshan City,the river water environmental quality has improved,which is consistent with the actual situation.So,the proposed method is feasible and effective.
