| 摘 要： | 结合重庆开县饮用水源地水质监测数据情况,对全县饮用水源地的水质进行模糊综合评价,采用熵权法赋权对水质进行了分级评价。2010～2011年,水质情况总体良好,绝大部分水质处于I类和II类。2011年下半年水质较其他时间有所退化,出现了两个III类水。这个变化趋势应该引起当地政府的高度重视。

| Abstract: | Based on the water quality monitoring results at the drinking water sources in Kaixian County, a fuzzy comprehensive evaluation with an entropy-based weight is employed to assess the water quality and classify the water quality grades in Kaixian County. On the whole, the water quality of the drinking water sources in 2010 and 2011 was good. The water grades were either gradeⅠ orⅡ for most of the water sources. Compared to the water quality in other months, the water quality during the second half gradeⅢ. The local authorities need to pay much more year of 2011 was degrading, with two water sources being attention to this change. |
