南水北调输水期间怀柔水库及京密引水渠水质分析

Analysis of water quality in Huairou reservoir and Jingmi diversion canal during the South-to-North water diversion

为了掌握怀柔水库及京密引水渠在输水期间的水质变化规律．对监测区域水质变化进行分析及评价，结果表明：2016—2017年不同监测点位以及整个监测区域不同季度水质均满足地表水Ⅱ类水质标准。本研究为怀柔水库及京密引水渠后续水质安全保障工作提供了基础。

In order to understand the water quality change regularity in different monitoring sites along the Huairou reservoir and the Jingmi diversion canal, the paper analyzed and assessed the water quality. The result showed that, the water quality met the surface water environment quality ]] class, which was assessed water quality from different monitor sites during 2016 to 2017 and different seasons in whole area. This result provided the basis for water quality safety management in Huairou reservior and Jingmi diversion canal.
