摘要
以某金矿地表水水环境质量为例,分别运用传统的单项标准指数法评价和物元可拓集分析理论对地表水水环境质量进行了评价,选取具有代表性的BOD5、CODcr、NH3-N、石油类、粪大肠菌群五项指标为待评物元,取Ⅰ至Ⅴ类水质标准对应的取值范围构造经典域物元矩阵,按照污染贡献率法确定各特征(评价因子)的权重,应用建立的水质评价物元模型计算出关联度max[K(jP)]=K2=0.14,得出该河流水环境质量属于Ⅱ级。实例研究表明,运用物元模型评价水环境质量,评价结果符合客观实际,具有较好的实用性。
Taking water environment quality of gold mining area as an example, respectively using the traditional single standard index method and matter-element analysis theory to evaluate the water environment quality. We select BODs, CODcr, NH3-N, petroleum, fecal coliform bacteria as matter-element, choose I to V water standard range corresponding to classical field matter-element structure matrix, in accordance with the pollution contribution rate method to determine the weight of factors, applying the matter-element analysis method to calculate the max correlation degree （max[Kj （P）]=K2=0.14）, eventually obtain the degree of the river water quality is Ⅱ. The results prove the new model is suitable to evaluate water environment quality and it can be applied in practice.
