The RF method based on grid-search parameter optimization could achieve a classification accuracy of 88.16% in the classification of images with multiple featurevariables. This classification accuracy was higher than that of SVM and ANN under the same featurevariables. In terms of efficiency, the RF classification method performs better than SVM and ANN, it is more capable of handling multidimensional featurevariables. The RF method combined with object-based analysis approach could highlight the classification accuracy further. The multiresolution segmentation approach on the basis of ESP scale parameter optimization was used for obtaining six scales to execute image segmentation, when the segmentation scale was 49, the classification accuracy reached the highest value of 89.58%. The classification accuracy of object-based RF classification was 1.42% higher than that of pixel-based classification(88.16%), and the classification accuracy was further improved. Therefore, the RF classification method combined with object-based analysis approach could achieve relatively high accuracy in the classification and extraction of land use information for industrial and mining reclamation areas. Moreover, the interpretation of remotely sensed imagery using the proposed method could provide technical support and theoretical reference for remotely sensed monitoring land reclamation.
