摘要
准确的湖泊水质评价是顺利开展水污染防治工作的重要保证.采用灰色关联投影法和变异系数定权法,对合肥柏堰湖2016年9月至2017年8月共12个月的水质进行综合评价.结果表明冬季12月柏堰湖水质最好,夏季8月柏堰湖水质最差;影响柏堰湖水质的主要因素是湖水中氮、磷元素的含量.该方法结果可信,实用性强,在水质评价中具有应用价值.
The accurate evaluation of lake water quality is an important guarantee for water pollution control. Grey correla-tion projection method and variation coefficient method were used to evaluate the water quality of Baiyan Lake in Hefei fromSeptember 2016 to August 2017. The results shows that the water quality of Baiyan Lake was the best in December in winterand the worst in August in summer, and the main index affecting the water quality of Baiyan Lake was the contents of nitro-gen and phosphorus in the lake water. The results of this method are reliable and practical, with high application value inwater quality evaluation.
