Quantitative analysis of Soil loss in the Plateau administrative territorial units of Suceava county

Beginning with the statement that the economic activities of the main sector occupy a majority share in Suceava Plateau, this study aims to highlight the negative impact that the use of the land has on soil. The determination of soil loss from the said area will be accomplished through a GIS analysis using the USLE model (Universal Soil Loss Equation), where, in addition to the land utilization will be taken into consideration a number of other factors regarding the climatic, soil and topographic particularities.  The result of this type of modeling permits an inventory of the soil loss values and the identification of areas where the admitted quality of soil loss is exceeded, therefore, being lost the main nutrient elements of the soil, decreasing fertility. The utility of the USLE model application is found in determining the crops alternation structures or in determining the soil protection measures. Moreover USLE model is an effective tool in defining a territory’s dysfunctions connected to the soil’s degradation, screening an eloquent image of the existing situation regarding the environmental quality in developing the land setup plan

LANDSLIDE SUSCEPTIBILITY IN THE RURAL AREA OF BUCOVINA

The territorial support of the Bucovina region is characterized by its complexity, this characteristic deriving primarily from the fact that it meets in its boundaries different properties, the western part being a mountainous region and the eastern one of plateau. Sketching an actual image of the existing dysfunctions of the region from a natural perspective requires an analysis of the susceptibility of landslides, this being one of the most common problems when it comes to the quality of the natural support of a geographic complex. The predisposed areas to this type of hazard will be outlined into a cartographic support according the semi-quantitative method governed in Romania by G.D. no 447/2003 which establish the elaboration and the content of natural hazards at landslides. In order to achieve this objective, it has been used G.I.S. technique both for the construction of vector and raster necessary data bases and for statistical analysis of the final results. Last but not least through the mentioned technique it can be identify the risk caused in the territory by landslides. One of the benefits of this study is the forecasting of regional development projects in rural areas from Bucovina
