摘　　要：本文以Landsat 8卫星OLI影像的Coastal aerosol、Red、Near Infrared(NIR)和SWIR1四个波段推导出一种适用于Landsat 8卫星OLI影像水体信息的提取公式(即LBV中的B变换公式),在此基础上构建新的水体信息提取模型(新的谱间关系模型):KT3+B-OLIRed-OLINIR+DN>0,并利用此模型分别提取淮南市周边地区和五河县周边地区的水体信息。实验结果表明:新模型能快速地提取大面积水体信息,而且具有较好的效果和较高的精度,能满足大面积的水体快速制图和土地利用/覆盖的分类。In this paper, a new formula of water body information extraction applicable to OLI image was deduced using four bands(including Coastal aerosol, Red, Near Infrared(NIR) and SWIR1) of Landsat 8 satellite, namely the B formula of LBV transform. Furthermore, a new spectral relation model, KT3+ B- OLIRed- OLINIR+ DN > 0, for extracting water body information, was created based on the new formula. Finally, the water body information of Huainan and Wuhe County was extracted based on the new model. Results showed that the new model could more quickly extract water body information of a large area, and had better effect and higher precision than other methods.Thus the new model could be used for quick mapping and land use/cover classification of water body in a large area.
