摘要
为解决水质评价中评价指标众多,存在复杂性、模糊性和不确定性等问题,采用基于指标变换值的模糊物元模型对克孜河河流2012年的水质进行评价,并与传统的单因子评价法和灰色关联分析法评价结果进行对比。结果表明:模糊物元评价得出不同时期河流水质级别均为Ⅰ级;基于指标变换值的模糊物元得出的评价结果与灰色关联分析法是一致的,与单因子评价法的评价结果在5月8日的取样值略有不同;基于指标变换值的模糊物元模型应用在该河流水质评价中是合理可行的,且计算简便实用。
Fuzzy matter-element model based on index transform values is adopted to evaluate the water quality of one river in 2012 in order to solve the problems in water quality evaluation index, such as numerous evaluation index, complexity, fuzziness, uncertainty, etc. The results are compared with evaluation methods by traditional single factor evaluation method and grey relation analysis method. The results show that river water quality grade is I at different stages according to the fuzzy matter-element evaluation. The evaluation results concluded from fuzzy matter-element based on index transform values are consistent with that of grey correlation analysis method. The evaluation results of single factor evaluation method are slightly different according to sampling value on May 8. It is rational and feasible to apply the fuzzy matter-element model based on index transform values in river water quality evaluation, and the calculation is simple and practical.
