摘要
为了解决集对分析法在环境质量评价中应用的问题,用集对分析法建立了河流水质评价模型,并应用该模型对阜新市大凌河支流4个断面监测点的7种污染因子监测结果进行实例分析。结果表明,各断面水质评价级别均为Ⅴ级。研究表明,采用集对分析法进行水质评价准确可靠,信息利用率高,具有客观性和合理性。因此,集对分析理论为河流水质综合评价提供了一种新的思路,所用理论方法和所建模型也可推广应用于其他领域。
The present paper is to introduce its authors＇ set-pair analysis method in analyzing and evaluating the monitoring results of 7 pollutants by taking the branch of Daling River in Fuxin as a case study. The actual monitoring and analysis work was done in 2003, with its actual average value of assessment parameter to Xi River （a branch of Daling River in Liaoning） and the environmental quality standards for the surface water quality made up into a pair set. The research helped to arrive at the conclusion that the water quality of all samples collected may belong to level Ⅴ Although all the monitoring results of the four monitoring points may ailbe categorized into level Ⅴ, it is still possible to find some difference among the samples taken from different spots. For example, the pollution situation with those taken from Gahaixi, Dongliang Bridge and Gaotaizi prove to be more serious, while those taken from the Moon Bay seem to be less serious. Thus, the analysis results show that the set pair analysis method for the river water quality assessment is realistic, comparatively accurate as well as reliable. It is also expected to be highly convenient, objective as Well as rationalistic, and, therefore, can be taken as an effective up-to-date analysis means for river Water quality assessment. Furthermore, the theory, the method, as well as, the model proposed here can also be extended to and adopted by some other related fields.
