摘要: 贴近度法作为一种模评价方法,已被广泛应用于土壤重金属污染水平和水环境质量的评价。本文针对优化后点位选择缺乏定量方法的现状,引入重心距离算法对贴进度法进行改进,使优化结果更具科学性和准确性。以浑河干流为研究区,使用改进后的贴进度法对浑河干流7个监测断面进行优化,采用T检验和F检验对优化结果进行验证,优化后的浑河干流监测断面减少为5个,优化后断面所反映的水质与优化前无显著差异,表明改进后的贴近度法在水质监测断面优化中实用性较好。

Abstract:

As a fuzzy evaluation method, the similarity method has been widely applied in evaluation on pollution level of heavy metals in soil and water environment. Due to lack of quantitative approach to point selection after optimization, this study improved the similarity method by integrating the method of the distance to the center of gravity in order to enhance the accuracy and rationality of results. The improved similarity method was applied to optimize 7 monitoring sections of the main stream of the Hun River. Then, the results were validated by Ttest and Ftest after optimization. The number of the water monitoring sections was reduced to 5 after optimization, and the water quality after optimization had no significant difference compared to that before optimization, which indicated that the improved similarity method has the advantage practical application the optimization of monitoring sections of water quality.
