THE CHANGES OCCURRED IN THE LAND USE FROM THE EASTERN PART OF ROMANIA AFTER 1989 - REMOTE SENSING AND GIS APPLICATION
Journal Title: Present Environment and Sustainable Development - Year 2007, Vol 1, Issue 1
Abstract
Les modifications intervenues dans la société roumaine après 1990 ont laissé des traces évidentes sur tous les aspects socio-économiques; cet article présente les principales changements sur l’utilisation du terrain et leur effects sur l’environnement. Le retour à la propriété privé à la suite des mesures legislatives - Loi 18/1991 et Loi 169/1977 – a boulversé tout le système d’exploitation du terrain, conduisant à un fort pullulemnt des parcelles agricoles. Le but de cet article est d’analyser les effects des mesures legislatives sur l’utilisation du terrain dans la region du nord-est de la Roumanie à l’aide de la Télédétéction et des techniques GIS mais aussi de souligner les difficultes rencontrées au fil du démarche de recherche. On a utilisé des images Landsat et Spot à coté des cartes topographiques et l’observation directe du terrain. Les changements identifiées peuvent etre reversibles (le passage de l’arable au paturage) ou definitive(le passage de l’arable au construction), dans le dernier cas l’effect sur l’environnement etant plus fort. On a constaté aussi des forts changements structuraux comme la fragmentation des parcelles d’exploitation, la densite croissante de l’espace bati dans les villes , la reduction des surfaces forestières etc.
