- Abstract:
- In this study, we used fractal analysis to monitor the space-time evolution of forest areas. By this method, we observed the degree of fragmentation/compaction and heterogeneity/homogeneity of forested, deforested and reforested areas. Changes undergone by the forest areas were analysed for the Northern Carpathian Mountains of Romania, the mountainous area that suffered the most extensive transformations in this respect, in Romania. The database used satellite images 654178 Landsat 7 ETM + for the period 2000-2014. For the assessment of forest areas, the database provided by the Department of Geographical Sciences, Maryland University for the 2000-2014 period, was used. The Fractal Fragmentation Index (FFI), Fixed Grid 2D Lacunarity (Lambda(FG2DL)) and Tug-of-War lacunarity (Lambda(T-o-W)) were used to monitor the degree of fragmentation of forested areas, respectively, the degree of heterogeneity and dispersion of deforested surfaces. The highest average annual decrease of forested areas was recorded in 2007 and 2012 due to the growing number of legally and illegally exploited. The results confirm that fractal analysis can provide important information on the space-time patterns of deforestation and reforestation that shows a continuous reduction.
