摘    要:无定河流域煤炭、石油和天然气的大规模开发利用给流域内水资源带来极大的安全隐患。该文利用2013—2016年榆林市流域内水质监测数据进行研究。结果表明:无定河流域的地表水综合污染指数在0.29~0.55,由于受到沿河区域人类活动的影响,2013—2016年除庙畔之外,其余各监测断面的总磷均有不同程度的超标;2013—2015年As、Hg、Cd、Pb均符合标准,2016年开始出现污染,Se于2015开始出现污染现象;石油类和阳离子表面活性剂在2013—2016年均出现不同程度的超标。为进一步改善无定河流域的水质,须全方位监控流域内水资源污染情况,并加强管理。 

关 键 词:无定河流域    水质监测    水质评价

Abstract:Large-scale exploitation of coal,oil,and natural gas in Wuding River Basin has brought a great security risks to the water resources in the basin.Water quality monitoring data from Yulin city in 2013—2016 was analyzed.Results showed that:comprehensive pollution index of surface water in Wuding River Basin was between 0.292 to 0.55,due to influence of human activities along the river,in 2013—2016,with exception of Miaopan,the TP of other monitoring sections have exceeded the standards.As,Hg,Cd,and Pb met the standards,in 2013—2015,but pollution began in 2016,and Se began to experience pollution in 2015.Both petroleum and cationic surfactants exceeded the standards in 2013—2016.In order to further improve water quality of Wuding River Basin,it is necessary to comprehensively monitor water pollution in basin and strengthen management.
