| 中文摘要: |
| 水环境质量评价是水环境保护和治理工作的重要组成部分，通过对苏州河武宁路桥断面的水质监测数据进行评价，将水质标准、评价指标及其特征值作为物元，对评价标准及实测数据进行归一化后，建立地表水质量评价模型的经典域、节域、权系数及关联系数，通过计算综合关联度确定水质等级。评价结果表明：通过对苏州河武宁桥断面的水质分析，该断面水质为Ⅴ类。这一评价结果符合客观事实，物元分析方法可以准确地对水质进行等级评价，具有较高的参考价值。 |
| 英文摘要: |
| The water environmental quality assessment is the important part of water environment protection and management. By monitoring and evaluation data of the Wuning bridge section water quality in the Suzhou river. The water quality standards and evaluation index and its the characteristic value as a matter-element , establish the classical domain, joint domain, weight coefficient and
correlation coefficient about the surface water quality evaluation model after the evaluation standards and the measured data normalizatioof. Through comprehensive correlation calculation to determine water quality level. The evaluation results show that the water quality of Wuning bridge section in the Suzhou rive, isⅤclass, the evaluation results accord with the objective facts.So the analysis of the element unit can accurately evaluate water quality level, it is of high reference value. |
