| 摘要: |
| 为了解广西农村地表水饮用水水源地水质状况，根据2015-2021年广西农村地表水饮用水水源地水质监测数据，分析广西农村地表水饮用水达标情况、时空变化和主要超标因子等。监测结果表明：2015-2021年，广西672个村庄地表水饮用水水源地的水质达标率为78.42%。水质达标率年际波动较大，为68.35%-88.89%。每年各季度之间水质变化明显，一、四季度水质优于二、三季度，且各季度达标率明显高于同年总体达标率。超标村庄空间分布较广，超标因子相对集中，主要为粪大肠菌群、总磷等，表现出与农村农业面源污染较强的相关性。桂东地区水质达标率较高，在88%以上，而桂西、桂南较低。综上，广西农村地表水饮用水水源地水质有所改善，但不稳定，建议进一步加强农村饮用水水源地的监测和保护。 |

| Abstract: |
| ：In order to understand the water quality status of rural surface drinking water sources in Guangxi,according to the water quality monitoring data of rural surface drinking water sources in Guangxi from 2015 to 2021,the compliance status,temporal and spatial changes and main exceeding standard factors of rural surface drinking water in Guangxi were analyzed.The monitoring results showed that from 2015 to 2021,the water quality compliance rate of surface drinking water sources in 672 villages in Guangxi was 78.42%.The inter-annual fluctuation of water quality compliance rate was large,and the rate of compliance ranged from 68.35% to 88.89%.The changes between quarters were obvious every year,and the first and fourth quarters were better than the second and third quarters,and the compliance rate of each quarter was significantly higher than the overall compliance rate of the same year.The spatial distribution of over-standard villages was wide,and the exceeding standard factors were relatively concentrated,mainly including fecal coliforms,total phosphorus,which showed strong correlation with rural agricultural non-point source pollution.The water quality in the east of Guangxi was higher,with a compliance rate of more than 88%,while that in the western and southern Guangxi was lower.In summary,the water quality of rural surface drinking water sources in Guangxi has been improved,but it is unstable.It is suggested to further strengthen the monitoring and protection of rural drinking water sources. |
