Abstract:

Based on Landsat-8 image and forest resources management survey data,different forest land types were classified by maximum likelihood classification (ML),neural net classification (NN),support vector machine classification (SVM) and decision tree classification (DT) methods,and then the precisions (P) of classifications were verified,and the performances of classifications were evaluated correlatively.The results show that the best performance was SVM (P=78.7%,Kappa=0.76),and the followings were NN (P=76.8%,Kappa=0.72) and DT (P=72.5%,Kappa=0.68),and the worst was ML (P=44.9%,Kappa=0.39).These results provide a theory basis for the rapid extraction of forest resources information of forestry science data platform.

Key words: remote sensing, forest resources management survey, classification
