沁河干流典型断面水质评价方法的应用

Application of Water Quality Assessment Methods on Typical Sections of Trunk Stream of the Qinhe River

应用单因子污染指数法、综合污染指数法和内梅罗综合污染指数法,对沁河干流山西境内孔家坡和润城两个典型断面2011-2013年水质状况进行评价,并将三种评价方法的结果进行了对比分析。结果表明,两个断面的现状水质均能达到相应的水质目标,某些时段有轻度污染。不同评价方法对断面水质的评价结果不完全相同,应进行综合分析和判断。

Single-factor contamination index method,comprehensive contamination index method,Nemerow multifactor index method were selected to evaluate the water quality of two typical sections in Shanxi province of trunk stream of the Qinhe River from 2011 to 2013,and the results were contrastive analyzed. The results show that water quality of Kongjiapo section and Runcheng section can both reach the corresponding water quality targets,and the water is polluted slightly in some period of time. The assessment results using different methods are not identical,and should be comprehensively analyzed and judged.
