maging analysis based on satellite images, RapidEye imagery was used to analyse and characterize Paniova Forest, a Natura 2000 Site. The studied perimeter is located in the Lugoj Plain, Timis County, Romania. A RapidEye satellite scene with 5 - multispectral bands was used. From a morphological point of view, the study area was analysed based on the parameters: Altitude, Slope (degree) and Slope exposure. In relation to DEM, 10 classes of the protected area were obtained (14.76 ha and 368.64 ha), in relation to Slope, 10 classes (0.75 ha and 469.29 ha), and in relation to the Slope exposure 11 classes (4.53 ha and 339.9 ha). The relationship between NDVI and MSAVI was described by a linear equation in relation to Altitude derived from SRTM mission, and by polynomial equations of 2nd degree in relations to Slope and Slope exposure. According to PCA, PC1 explained 67.91% of the variance, and PC2 explained 32.033% variance with reference to DEM classes; PC1 explained 80,927% variance, and PC2 explained 18.576% variance with reference to Slope; PC1 explained 66.592% variance, and PC2 explained 33.235% variance with reference to Slope exposure.
