摘要
贴近度法是一种模糊评价方法,现如今,在水质评价中已被大量使用。为了合理设定水质监测断面,节约监测成本,以吉林省松花江干流为研究区,用贴近度法对吉林省松花江干流12个监测断面进行优化,并结合水环境管理的实际需求,对优化结果进行了修正,优化后监测断面减少为8个并已用t值检验法完成检验。而水质在优化前后没有明显的变化,说明贴近度法在优化水质监测断面中是十分实用的。
As a model evaluation method,similarity method has been widely applied to evaluate water environment quality.Taking the Songhua River as the research area,the similarity method was used to optimize the 12 monitoring sections in the area.The t-test was used to verify the optimization results. After optimization,the monitoring section of the Songhua River reduced to8,showing no significant difference between the quality of water and that before optimization,which shows that similarity method is better in water quality monitoring section optimization.
