摘要
由集对分析理论导出了水环境质量评价的新模型,将水质实测指标与分类标准作为集对,通过对评价级别和实测数据归一化后,得到模型的平均联系度,建立了水质评价的集对分析模型。并以九寨沟五彩池水环境质量为例,选取具有代表性的CODcr、DO、NH3-N、TP、粪大肠菌群五项指标及其对应的Ⅰ至Ⅴ类水质标准的取值范围构造集对,建立了水质评价集对模型,计算出平均联系度,得出该九寨沟五彩池水环境质量属于Ⅰ级。实例研究表明:运用集对分析模型评价水环境质量,评价结果符合客观实际,方法是可行的,具有较好的实用性。
The peper derived out the new model of water environment quality assessment from set pair analysis theory,the measured water quality indicators and classification standards as set pair,through the evaluation level and the measured data normalized,got an average connection degree to establish set pair analysis model of the water quality assessment. Taking Jiuzhaigou Wucaiche water environment quality for example,selecting a representative CODcr,DO,NH3-N,TP,fecal coliform five indicators and their corresponding GradeⅠ to Ⅴ standard range structure set right,established a set of water quality evaluation model to calculate the average connection degree,obtained the Jiuzhaigou Wucaiche water environment quality belongs to gradeⅠ. Empirical study indicated that set pair analysis model can be used to evaluate water environment quality,the evaluating results are objective and realistic,approach is feasible and has good practicability.
