三峡水库四期试验性蓄水前后嘉陵江饮用水源水质变化规律分析

Drinking Water Quality Analysis of the Jialing River During the Fourth Test of Water storage in the Three Gorges Reservoir

三峡工程四期于2008年11月开始试验性蓄水,库区蓄水水位达到172.4米,位于库区末段的嘉陵江特别是渝中区段的水文情势已开始发生一些变化,为研究三峡水库蓄水前后嘉陵江大溪沟饮用水源地水质变化状况,渝中区环境监测站自三峡水库四期试验性蓄水开始,每月定期对嘉陵江大溪沟饮用水源地水质进行监测,并对蓄水前后水质变化情况进行比对分析,以期找出其变化的规律。

The four-test water of the Three Gorges Reservoir began in November 2008, the reservoir water reached 172.4 meters, the Jialing River hydrological situation has begun to place some changes, especially the last paragraph of Yuzhong District section. In order to study the changes in water quality conditions of The Jialing River Da Xigou drinking water source before and after the four-test water of the Three Gorges Reservoir, Yuzhong District environmental monitoring stations began to monitor the situation of the Jialing River monthly from the four-test water of the Three Gorges Reservoir, contrast analyzing the water quality in order to find the changing law.
