摘　　要：以2015年Landsat8多光谱遥感影像作为基本信息源,在各地物光谱特征差异分析的基础上,采用谱间关系法与阈值法,构建不同水质水体提取模型,并结合实地水质监测数据及污染源数据,对提取结果进行精度评价与分析。结果表明,基于该方法能将一般水体、富营养化水体与其他地物区别开来,可以准确有效地获取不同水质的水体信息。With the Landsat8 multi-spectral remote sensing image in 2015 as the basic source of information, on the basis of spectral characteristic differences analysis, using spectrum correlation and threshold method, extraction model of water body with different water quality types was constructed, and combined with the field monitoring data of water quality and pollution source data, accuracy evaluation and analysis on the extraction results was conducted. The results showed that this method can distinguish the general water body, eutrophication water body from other objects, can accurately and efficiently to obtain the information of different water quality.
