| 摘 要： | 应用基于相对差异函数的可变模糊集理论,对黄河达拉特旗八大孔兑地表水水质进行评价,在计算相对综合隶属度时采用不同的参数组合,并与物元可拓法和综合水质标识指数法评价结果进行对比分析。结果表明,模糊可变评价方法克服了其他评价方法的片面性,提高了结果的可靠性和合理性。对于评价指标以区间值表示标准值的水质综合评价,能够有效解决区间值对评价结果的影响,获得更为合理准确的结果。 |

| Abstract: | The fuzzy invariable assessment theory based on the relative difference function was used to evaluate the surface water quality of eight rivers in Dalate Banner. The comprehensive membership degree was calculated with different combinations of parameters. Compared with the matter-element extension and comprehensive water quality identification index method, this new method is more reasonable and reliable because it uses interval values instead of single values and it can prevent the interval value from impacting the evaluation results. |
| Keywords: | fuzzy variable assessment relative difference function matter-element extension method comprehensive water quality identification index method water quality evaluation |
