| 摘要: |
| 为了解南流江水质变化情况，本研究基于2016年、2019年和2020年共3年的南流江水质监测数据，运用水质标识指数法，探究南流江全流域的空间分布特征、年际变化特征及其变化原因。结果表明：南流江中上游的玉州区、福绵区、博白县的水质较差，主要污染因子为氨氮、总磷，这与南流江流域的禽畜养殖业及生活污水排放有关，但经过综合整治，南流江的水质趋于改善。本研究结果可为下一步南流江精细化治理提供数据支撑。 |

| Abstract: |
| In order to understand the changes of water quality in the Nanliu River,based on the water quality monitoring data of the Nanliu River in 2016,2019 and 2020,the water quality identification index method is used to explore the spatial distribution characteristics,interannual variation characteristics and change reasons of the whole basin of the Nanliu River in this study.The results show that the water quality is poor in Yuzhou District,Fumian District and Bobai County in the upper and middle reaches of the Nanliu River.The main pollution factors are ammonia nitrogen and total phosphorus,which is related to the livestock breeding industry and domestic sewage discharge in the Nanliu River Basin.However,the water quality of the Nanliu River tends to improve after the comprehensive improvement of the government.The results of this study can provide data support for the next step of the fine governance of the Nanliu River. |
