Abstract:

The present paper analyzes land use evolution in Rebricea basin, mainly with insights into the dynamics of the forested surfaces, which are easier to interpret on diverse sets of cartographic materials. Thus the study compares cartographic materials from different periods (1769 – up to the present): the map of the Russian general F.G. Bawr, 1:280,000; the Russian map scaled 1:420,000 from 1828-1829, published in 1835; the topographic map from 1915, 1:200,000 and the topographic maps from 1972-1974, 1:200,000. The dynamics of the forested surface is very clear, the materials indicating a constant decrease of the forest surface. Nowadays,the analyzed basin is dominated by arable terrains, mainly in the central part of the basin, on divides and structural surfaces that offer better conditions for the development of crops. Areas less favorable are occupied by pastures, mainly in the floodplains, frequently affected by gleyzation or salinization, or the upper parts of the slopes, with higher declivities and thus erosion processes. Forests occupy the higher parts of the landscape, mainly in the northern part of the basin, but also with extensions on the divide between Vasluie and Rebricei. Bushes also occupy consistent surfaces, in the areas of recent deforestations.
