Abstract


This work evaluated the distribution of vegetation in slope classes as subsidy analysis of degradation of the municipality of Soledade through the use of GIS and remote sensing techniques using algebraic language and modeling. We used Landsat TM-5 to generate the IVDN images and SRTM to generate the map of slope. As a result we obtained maps of vegetation and the distribution map of vegetation in slope. It can be concluded that there was a recovery of the local vegetation, as the class of sparse vegetation, dense transition and found an increase of 20.53% 33.46% and 6.06% respectively, the vegetation classes are distributed in their most classes of nil slope and mild totaling 530.16 km2 accounting for 94.53% of the total area, and slope classes moderate, strong, very strong and extremely strong totaling 3.7 km2 and Litholic Neosols occur in eutrophic soils.
