采用综合污染指数法，评价了六磊塘2005~2012年间在丰水期、平水期、枯水期和全年的水质达标情况，计算了主要污染物的污染负荷，得到了水质的时间变化特征。结果表明，2005~2012年，六磊塘水质呈现改善趋势，水质整体呈现轻到中度污染；枯水期水质污染最重，丰水期和平水期水质污染相对较轻；各主要污染物中，氨氮的污染负荷最大，五日生化需氧量和高锰酸盐指数的污染负荷最小。研究结果为六磊塘的地表水质监测和污染防治等工作提供了重要依据。

Standard reaching results of water quality of Liuleitang River were evaluated in high water period,common water period,low water period and whole year between 2005 to 2012 by using comprehensive pollution index. The pollution loads of main pollutants were cal-culated and temporal variation of water quality was analyzed. The results showed that the water quality of Liuleitang River was improved and it was slightly to moderately polluted between 2005 to 2012. The water quality in low water period was most seriously polluted and the water quality in common water period and in high water period were relatively light. In main pollutants,the pollution load of ammonia nitrogen was highest and the pollution loads of five day biochemical oxygen demand and permanganate index were lowest. The results would provide impor-tant reference for surface water quality monitoring,pollution prevention and control of Liuleitang River.
