| 摘 要： | 为实现水体黑度和臭度的独立评价，以四川省11个市17条黑臭或曾黑臭的河道为研究对象，利用相关性分析法、主成分分析法，提取出影响河道水体黑度和臭度的特征因子，采用改进模糊综合评价法和基于K-均值聚类的主颜色提取法搭建出黑臭程度独立评价模型。结果表明：影响河道水体发黑的特征因子是总铁、COD和DO；影响河道水体发臭的特征因子是COD、NH3-N、TP和DO；改进模糊综合评价和主颜色提取模型对河道黑度和臭度的独立评价与实测值误差基本在一个等级以内的准确率为85.7%。河道的黑臭程度独立评价模型的确定能够实现对城市河道水质更为客观与快速的评价，为黑臭水体针对性治理与水质提升提供理论依据。

| Abstract: | In order to realize the independent evaluation of black and odorous water,17 black and odorous or once black and odorous rivers in 11 cities of Sichuan Province were taken as the research objects.The correlation analysis and principal component analysis were used to extract the characteristic factors affecting the degree of black and odor of rivers.The improved fuzzy comprehensive evaluation method and the dominant color extraction method based on K-means clustering were used to build an independent evaluation model of black and odor.The results showed that the characteristic factors affecting the blackness of water were total Fe,COD and DO.The characteristic factors affecting the odor of water were COD,NH3-N,TP and DO.The accuracy rate of the improved fuzzy comprehensive evaluation and the main color extraction model for the independent evaluation of river blackness and odor was 85.7%,which was basically within one grade.The determination of the independent evaluation model of the black and odorous degree of rivers can realize a more objective and rapid evaluation of the water quality of urban rivers,and provide a theoretical basis for the targeted treatment of black and odorous water bodies and the improvement of water quality. |
