Abstract:
Water quality assessment is a very ordinary work in the field of water environment, and the evaluation methods generally involve single factor evaluation method and comprehensive evaluation method. However, choosing single factor evaluation method or comprehensive evaluation method to evaluate water quality is something of a dilemma. It is noteworthy that researching how to combine the single factor evaluation method and the comprehensive evaluation method to assess water quality is still given less concern. In order to achieve the above research, this paper learns from the calculation idea of harmony degree equation to put forward a evaluation method of harmony degree equation (HDE) applied to water quality assessment which includes single factor evaluation and comprehensive evaluation. HDE evaluation method not only can replace the comprehensive evaluation method, but also can represent the single factor evaluation method -- that is, it has successfully combined the single factor evaluation method and the comprehensive evaluation method. In this paper, the concrete steps of HDE evaluation method were expounded in detail and cases study was carried out to explain the application process. Research results in this study can expand the application fields of harmony theory, promote the unity of water quality assessment methods and provide reference for other comprehensive assessment.
