摘要:The aim of this study was to monitoring land-use changes of Zagros forest in Iran, using four methods; namely, Green Tasseled Cap (GTS), Image Ratio (IR), Normalized Difference Vegetation Index (NDVI), and PCA 2 Difference (PCA). This study was done on satellite images of TM sensor (1988) and ETM+ sensor for 2013. The overall accuracy and Kappa coefficient were used to determine the accuracy of the produced maps. The results of the accuracy evaluation showed that PCA 2 differencing method with overall accuracy and Kappa coefficient of 97 and 0.95 respectively is the most accurate method and IR method with overall accuracy and Kappa coefficient of 75 and 0.61 respectively, is the least accurate method. Results showed that extensive changes have happened in these areas which are generally descending in a way that 60.51% of natural lands have changed over the past 25 years. In other words, in this area 2.41 percent of natural lands are being converted every year.
