| 摘 要： | 以2009—2015年的花溪河水质监测数据为依据,用营养状态质量指数法评价巴南区花溪河的富营养化水平。结果表明:按营养水平划分依据规定,南湖断面水质较好且其富营养化水平为贫营养化水平,花溪河中下游监测断面石龙桥和敬老院都为富营养水平,石龙桥水质最差,主要污染因子为氨氮、总氮、总磷。石龙桥与敬老院断面间,丰水期、枯水期、平水期的营养质量指数值(NQI)都大于3,营养等级均为Ⅲ级。

| Abstract: | On the basis of monitoring data from 2009 to 2015 of Huaxi River,eutrophication level of Huaxi River was analyzed with nutrient quality index method.The results showed that the water quality of Nanhu Lake monitoring section was the best and oligotrophication.The eutrophication level of Shilong bridge and Jinglaoyuan section was eutrophic level,and the water quality of Shilong bridge was the worst.The main pollution factors were NH4-N,TN and TP.The nutritional quality index values (NQI) of Shilong bridge and Jinglaoyuan section were greater than three,and belonged to Ⅲ nutrition degree. |
