| 摘 要： | 将主成分分析和综合指数评价法相结合,对绵阳市饮用水水源地的水质现状进行了评价.结果表明,2006-2010年饮用水水源地水质呈下降趋势,特别是2010年水质污染程度严重,主成分载荷值最大者为BOD5,重金属汞的单因子指数为2,无法满足Ⅱ级水源地(Ⅲ类地表水)标准要求,并根据水质污染现状,提出了相应的保护水源地水质的措施.

| Abstract: | The situation of drinking water source quality in Mianyang City was evaluated combined principal component analysis with comprehensive index method. The results showed that the drinking water source quality presented the tendency of decrease from 2006 to 2010, especially the water quality pollution was very serious in 2010, the maximum load value of principal component was BOD5, the single factor index of heavy metal mercury was 2, it could not satisfy the standard requirement of grade II of water source area（ category Ill of surface water）. The measurement of protection of water source quality was put forward according to the situation of water quality pollution. |
