灰色聚类样点排序法在地表水环境质量评价中的应用

运用灰色聚类样点排序法对地表水环境质量进行评价,并将该方法与灰色聚类法进行比较。结果表明,灰色聚类样点排序法适用于各测点的实测污染质量浓度都在级别标准范围内无规律地变化、各污染物的标准值之间差异大时;而等斜率灰色聚类法只适用于当各测点的实测污染质量浓度都在级别标准范围内较有规律地变化、各污染物的标准值之间差异不太大的时候。应用灰色聚类样点排序法对浑河抚顺段水环境质量进行评价是比较合理的。

Application of Obscure Clustering Sample Permutation Method on Environmental Quality Assessment of Surface Water

In this article the obscure clustering sample permutation method was used in the water environmental quality assessment and we also used isogradient obscure clustering method to compare the resull.The result indicated that isogradient obscure clustering method was feasible when every actual measuring points orderly change in level standard range and the difference in every contamination's standard was not too big,the water environmental quality assessment of Hunhe in Fushun used the obscure clustering sample permutation method was reasonable.
