乌江流域沿河段近五年水质现状变化趋势分析

Analysis on Water Quality of Yanhe Section in Wujiang River Basin in the Past Five Years

通过对2013-2017年乌江流域沿河段水质监测资料进行分析,总结出乌江流域沿河段水质变化趋势。调查该段水质污染的主要原因,提出对策措施,为乌江流域的治理提供一定的参考。调查结果表明影响乌江流域沿河段水质的主要原因是总磷污染,且总磷的主要污染负荷来自乌江上游。通过历年监测结果对比分析,该段总磷污染总体呈下降趋势,逐渐趋于好转。

The change trend of water quality through the analysis of environmental monitoring data of Yanhe section in Wujiang river basin from 2013 to 2017 was summed up. The main causes of water pollution in this section were investigated,and corresponding countermeasures were put forward to provide some reference for Wujiang river basin improvement. The results showed that the main pollutant of Yanhe section in Wujiang river was total phosphorus,and the main pollution of total phosphorus was from the upstream of Wujiang river. Meanwhile,through the comparison and analysis of monitoring results of the past five years,the total phosphorus pollution in Yanhe section was decreasing and gradually improving.
