利用数学模型评价胶州湾水质状况

Evaluate Water Quality Condition of Jiaozhou Bay with Mathematical Models

依照2005年胶州湾水质的监测资料,采用两种数学模型方法——单因子指数法和模糊综合评价法分别进行水质现状的评价。通过计算得出结论:(1)胶州湾的东北部粪大肠菌群和无机氮超标,西北部无机氮严重超标,东南部粪大肠菌群超标,(2)采用熵权赋值法确定权重的模糊综合评价法的评价结果并不能体现水环境质量的实际情况,应该选取其他方法。

According to the monitoring data of water quality of Jiaozhou Bay in 2005 , we used two kinds of mathematical model method --- single factor index method and fuzzy comprehensive evaluation method to e-valuate water quality condition. The calculated conclusions were: (1) Fecal coliform bacteria and inorganic ni-trogen exceeded the standard in the northeast of Gulf of Jiaozhou, inorganic nitrogen seriously exceeded the standard in the northwest, fecal coliform bacteria exceed the standard in the southeast. ( 2 ) The evaluation results of fuzzy comprehensive evaluation method with the entropy weight assignment method can not reflect the actual situation of water environmental quality, so other methods should be chosen.
