摘要
通过对萍水河监测断面水质监测数据的分析,利用内梅罗污染指数法及秩相关系数法进行水质评价,分析了"十二五"期间萍水河水质情况及其变化趋势,阐述了萍水河的水质空间分布规律。结果表明:萍水河断面水质以Ⅱ类、Ⅲ类为主,水质总体较好,但呈下降趋势;其上游水质较好,中游较差,下游略有好转,麻山河等萍水河支流水质较好。
Based on the monitoring data of water quality of Pingshui River, the situation of water quality and the variation trends of Pingshui river from 2011-2015 were analyzed, the spatial dist-ribution and the change of water quality of Pingshui River was clarified. The results showed that the water quality of the upper reaches of Pingshui River mainstream was good, the middle reaches water quality was poor and the water quality of the downstream was slightly better. The water qualities of some tributaries such as Mashan River were good.
