中文摘要:
      根据2006~2015年南四湖90个水质点位的监测数据,选用了水质综合污染指数和综合水质标识指数等分析评价方法,对南四湖不同监测点位、年际和春秋的水质变化趋势进行综合评价与比较分析。结果表明,南四湖水质总体上得到了大幅度改善,水质整体达标。其中,水质指标CODCr、CODMn、TP、TN、NH3 N的下降率分别为47%、-3%、33%、60%、80%;水质综合污染指数P由1.75下降至0.89,综合水质标识指数I由4.620下降至3.200;南四湖水质由北向南逐渐变好,春季比秋季水质好,部分区域的水环境质量仍需进一步提升。
英文摘要:
      This research investigated the monitoring data of 90 sites in the Nansi lake during the year 2006 2015.The monitoring data was used to analyze and compare the water quality variation trends of the lake in different monitoring sites, annual and spring by using water quality comprehensive pollution index and comprehensive water quality identification index evaluation methods. The results show that the water quality has been greatly improved and the overall water quality reaches the standard on the whole. The reduction ratio of CODCr, CODMn, TP,TN and NH3 N is 47%,-3%,33%,60% and 80%, respectively. The water quality comprehensive pollution index P decreases from 1.75 to 0.89, and the comprehensive water quality identification index I decreases from 4.620 to 3.200. The water quality from north to south gradually becomes better, water quality in Spring is better than that in Autumn. The water quality of environment in some areas still needs to be improved further.
