摘　　要：利用Sentinel-2卫星遥感影像对南宁市主要水体的五日生化需氧量、氨氮、总磷、总氮等非水色水质参数进行反演研究,经验算反演结果与传统监测结果水质类别在一定程度上吻合,但结果正确率不够高,还无法取代传统检测评价。卫星遥感影像反演推算水质情况具有快速、高效、监测覆盖面宽等优势,可用于水质监测站点规划以及水域污染情况预估。By use of Sentinel-2 satellite remote sensing image,inversion study was conducted on the non-water color water quality parameters such as 5-day BOD,ammonia nitrogen,total phosphorus,and total nitrogen of main water bodies in Nanning City.The inversion results of empirical calculations are consistent to certain extent with the tradi⁃tional monitoring results of water quality categories,but the accuracy of the results is not high enough,so it cannot replace traditional detection and evaluation yet.Inversion of water quality with satellite remote sensing images has the advantages of fast,high efficiency and wide monitoring coverage etc.,and can be used for water quality monitor⁃ing station planning and water pollution prediction.
