ANALYSIS OF SPATIAL AND TEMPORAL CHANGES IN THE LAND USE IN THE HYDROGRAPHIC BASIN OF THE CRISUL ALB RIVER, THROUGH GEOMATIC TECHNIQUES

Abstract

The land use, in any geographical region, is constantly changing, under the action of natural and/or anthropogenic factors. The changes produced on land use categories can have positive and/or negative consequences on terrestrial ecosystems or can be reflected in the profile of human activities. In this context, the purpose of the research included in this study was to identify the changes produced in time and space in the land use, in the Crisul Alb river basin, over a period of approximately thirty years. Starting from the results obtained, by quantifying the "mobilized" surfaces, an alarm signal was raised on the risks associated with these changes or their benefits were highlighted. In rural areas, in general, but also in the case of the study area, there were situations of afforestation of grasslands, in contact with forestry, the abandonment of fruit plantations and the transition of these lands to other ways of use. On the other hand, in areas with agricultural activities, accessible and better populated, the expansion of arable land and the establishment or "revitalization" of fruit plantations was highlighted, Based on the results obtained in this study, it can be stated that monitoring changes in land use is particularly important in management strategies, at local and regional level.
