中文摘要：
针对水质评价工作,借鉴和谐度方程计算思路,提出和谐度方程（HDE）评价方法,并应用于水质评价（包括单因子评价和综合评价）中。HDE评价方法既可以代替综合评价方法,又可以表达单因子评价方法,即统一了单因子评价方法和综合评价方法。详细介绍了HDE评价方法的具体步骤,并举例说明其应用过程。研究既拓展了和谐论理论方法体系的研究领域,又促进水质评价方法的统一,并可为其他综合评价所借鉴。
英文摘要：
Water quality assessment is a kind of 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 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 learned 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 included single factor evaluation and comprehensive evaluation.HDE evaluation method could not only replace the comprehensive evaluation method,but also represent the single factor evaluation method：that is,it had 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.The results of this study can expand the application fields of harmony theory,promote the unity of water quality assessment methods and provide references for other comprehensive assessment.
