Research on Identification of Degraded Lands in Transylvanian Plateau Using G.I.S. Spatial Analysis
Identifying damaged lands in Plateau Transylvanian based on space analysis, is based on combination of thematic layers, NDVI item and inclination, for realizing another thematic field that contains areas with the same characteristics in terms of theirs attributes. NDVI item had been analyzed for a large territory, Plateau Transylvanian, and complex, referring to clime and landscape that induce a series of differences in vegetation and by default in the level of vegetation covering in this territory. Reported at all area that had been studied, the vegetation free lands, is represented by 16% of all and the vegetation covered areas is 84%. From quantitative data, the damaged surfaces amount, derived after GIS space analyzing model, it can be observed clearly on the amount of studied territory that the amount of damaged fields is very small 7%, against relatively stable fields that totals 93%. The 128295 identified lands, sign up as territorial extension between 0.23-209 ha. The largest territorial extension is represented by areas that range between 0.23 -7.3 ha, in proportion of 88%, larger than 7.3 Ha areas represent 12% of studied territory. Transylvanian Plain is the subunit that contains the largest area of damaged lands (13.81%), resulted by shaping, followed by Plateau Somesan (10.17%) and Plateau Tarnavelor (5.11%). The smallest damaged area territorial extension is noted on Subcarpathians Transylvania (2.9%).
