Abstract. Spontaneous urban development, specific to East European cities in the post-socialist period, produces permanent land-use changes. The study aims at analyzing this phenomenon for the particular case of the North East Development Region of Romania. Although as a way of manifestation there are many similarities at regional level, the behavior of urban systems and land-use changes are influenced by many local factors. For this study, updated data provided by Corine Land Cover were capitalized, and the analysis were carried out in temporal stages – 1990 – 2000 – 2006 – 2012 – 2018 using the ArcGis software. In terms of assessing the consequences of urban development, the analysis concentrates on permanent changes that can indicate the penetration of urban space in rural areas. The largest area of land-use category transformed into artificial surfaces belongs to the agricultural sector. The challenge is to analyze the magnitude of this phenomenon, the main consequence being the consumption of productive land, and to see if its perpetuation and intensification contravenes the principles of sustainable development.
Resume. Le développement urbain spontané, propre aux villes d'Europe de l'Est dans la période postsocialiste, produit des changements permanents d’occupation des sols. L'étude vise à analyser ce phénomène au niveau régional, sur les surfaces de la Région de Développement du Nord-Est de la Roumanie. Malgré les similitudes dans sa manifestation qui existent au niveau régional, le comportement des systèmes urbains et les changements d’occupation des sols sont influencés par de nombreux facteurs locaux. Pour cette étude, ont été capitalisées les données mises à jour et fournies par Corine Land Cover, l'analyse étant réalisée par étapes temporelles - 1990 - 2000 - 2006 - 2012 - 2018 à l'aide du logiciel ArcGis. En termes d'évaluation des conséquences du développement urbain, l'analyse se penche sur les changements permanents qui peuvent indiquer la pénétration de l'espace urbain dans les zones rurales. La catégorie d'occupation des sols dont la plus grande surface a été artificialisée appartient au secteur agricole. L'enjeu est d'analyser l'ampleur de ce phénomène, dont la principale conséquence est la consommation de terres productives, et de voir si sa perpétuation et son intensification contrevient aux principes du développement durable.
