| 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. |
