【 摘 要 】

This study is based on remote sensing tools and landscape change indicators. It produced a mapping of landscape dynamics in Mogods between 2000 and 2015. Landscape dynamics are addressed through the decision tree of J. BOGAERT et al. (2004). Dissection and perforation of the maquis have led to fragmentation and reduced spatial connectivity. The appropriation of new agricultural land is effected by the opening of clearings and the nibbling of wooded areas. In this respect, fire is an effective and highly used means. The diachronic study, however, is partially distorted by the improvement of the resolution of the Landsat images since 2013.
