基于物元分析法的温榆河水质评价初步研究

Preliminary study on water quality evaluation of Wenyu River based on matter element analysis

近年来,在社会经济发展的同时,河流水污染带来的环境问题也日益突出。发源于北京昌平的温榆河,污染治理和改善水质问题已迫在眉睫。本文在对温榆河进行水质调研并对数据进行处理的基础上,通过构建经典域、节域、权系数及关联度,建立温榆河水质评价的物元模型。结果表明:2018年温榆河水质为Ⅴ类,与实际情况相符,水质状况不容乐观。同时也反映了物元分析法在水质评价中计算简捷,结果直观,具有能够综合反映水质状况的特点。

In recent years,along with the social and economic development,the environment problems has been worsen caused by the water pollution of rivers.Wenyu River,originated in Changping district in Beijing,its follution control and improvement of water quality are imminent.Based on the investigation of the water quality of Wenyu River and the data processing,this paper establishes a matter-element model for water quality evaluation of Wenyu River by constructing classical domain,nodal domain,weight coefficient and correlation degree.The results show that the water quality of Wenyu River in 2018 is Class V,which is consistent with the actual situation and the water quality is not optimistic.At the same time,it also reflects that matter-element analysis method is simple in calculation and intuitive in results during water quality evaluation,which can comprehensively reflect water quality conditions.
