Abstract According to the problems of remote sensing information extraction in lake salinity level of Badain Jaran desert, the authors put forward a method based on support vector machine (SVM). In this paper, the authors adopted Landsat8 OLI remote sensing image as the data source, completed the image preprocessing such as geometric correction, image registration and mosaicking. With the help of the RS and GIS technology, the authors successfully extracted the information of lake salinity levels of the Badain Jaran desert. The results show that the proposed method can effectively solve the problems of less samples and the information extraction of lake salinity levels when the spectral information is confused, and hence has the reference value and can be promoted to other similar situations.
