基于变异系数权重的水质评价属性识别模型

Attribute recognition model-based variation coefficient weight for evaluating Water Quality

运用水质评价标准的指标数值变异系数确定其权重,提出了新的用于水质综合评价的属性识别模型.采用松花江哈尔滨江段的水质监测资料说明该方法的操作过程以及评价结果的可靠性,评价结果得出,松花江哈尔滨江段的水质已达Ⅲ级,该结果与层次分析法所得的结果相同,从而验证了该模型用于水质综合评价是可行的.

The indexes weight is decided by the Variation Coefficient of the value of evaluated indexes of water quality standard, the new attribute recognition model is proposed and applied to evaluate water quality. The used process and the reliability of the new method are explained by real survey water quality data of Harbin a certain reach of the Songhua River. The result is that the water quality of Harbin a certain reach of the Songhua River reach Ⅲ grade, and this result agree with that of the analytic hierarchy process （AHP） method. It validates the new model is feasibility in synthesis evaluating water quality.
