| Popis: | This study aims to analyze the changes of forest cover in the region of Belezma-BATNA in North Algeria, during a period of 31 years (1986 to 2017), based on the use of remote sensing data (diachronic analysis of satellite images Landsat) by calculating indices (NDVI and NDWI). The results revealed significant changes during this period. Regressive changes in vegetation cover, particularly between 2000 and 2017. This degradation is mainly located in the southern and southeastern part of the Belezma forest resulting from several natural and anthropogenic factors. It can be considered that drought is one of the main causes causing the regressive change of forest during this period with other factors that promote this degradation such as overgrazing, fire, phytosanitary problems (caterpillar processionary), etc. |
