改进的物元分析法在水质监测断面布设优化中的应用

依据传统物元分析法的原理,使用层次分析法结合熵权法的组合权重法对物元分析法的权重计算进行改进,对关联度进行聚类分析,使传统的物元分析法得到改进与拓展。以浦阳江干流9个水质监测断面,主要监测指标COD_(Mn)、COD、TP、NH)3-N及氟化物的2012年监测数据为基础,采用改进的物元分析法对水质监测断面进行优化,将原有9个断面优化为7个断面,并对优化结果进行一致性检验,结果显示,改进的物元分析法优化结果准确、有效。

Application of improved matter element analysis method to optimization of water quality monitoring sections

According to the principles of traditional matter element analysis methods, the combined weight method, which is the combination of the AHP method and the entropy method, was used to modify the weights in the matter element analysis method. Then, the relevance was studied through cluster analysis, and thus the traditional matter element analysis method was improved and expanded. Based on monitoring data involving COD_Mn, COD, TP, NH₃-N, and fluoride, at nine water quality monitoring sections on the main stream of the Puyang River in 2012, the improved matter element analysis method was used to optimize these water quality monitoring sections. As a result, the original nine sections were decreased to seven sections after optimization. The results were verified by the consistency test, indicating that the improved matter element analysis method can provide accurate and effective optimization results.
