Abstract:In order to improve the the accuracy of remote sensing classification and extraction of land use information in mining areas, by using multi-source data fusion technology and GF-2 satellite data, the land use information of open pit mining area in Yuzhou City, Henan Province was extracted based on combining support vector machine and object-oriented method. The results showed that the overall accuracy of mining area information extraction based on combing support vector machine and object-oriented method was 86. 44% , and the Kappa coefficient was 0. 83 ,which was better than that of the combined K-nearest neighbor algorithm and object-oriented method. It showed that this method had ideal accuracy in mining area information extraction, and could provide reliable technical support for environmental monitoring and scientific management of mining areas.
