VULNERABILITY OF SOIL COVER IN RELATION TO CLIMATE TREND ARIDIZATION IN THE CENTRAL PLATEAU OF DOBROGEA

Increasingly obvious trend of climate change data through a gradual warming of the atmosphere, making the south-eastern Romania one of the most vulnerable regions in terms of the desertification phenomena that occur at the soil level. The geographical position of Dobrogea is routed along the isotherm of 11oC, which makes the plateau to register the lowest values of the index of dryness (Iar) from the whole Romanian territory, between 0.25 - 0.65 so it is that this aridization tendency to induce the climate soil cover a different graduations of various genetic types of soil vulnerability, which is due to both variability of soil formation deposits, the characteristics of topography, groundwater and salinization processes (salinization / sodization) etc. Pedological mosaic of the plateau requires the recruitment of vulnerable groups of soils as a coherent management through sustainable management in an area where biodiversity is a tendency to decrease markedly.
