Abstract:
Are analyzed qualitatively and are compared the gradients of evapotranspiration on both natural regions of Paraguay, taking as base the patterns of vegetal formations exist in base to satellite images provided by the sensor MODIS/NASA, furthermore the variations intra seasons depending of the months of year and the presence of vegetation and are described qualitatively the Normalized Differences Vegetation Index (NDVI), considering some climatic parameters. The Oriental region present gradients less high that in the Chaco, directly connected with the patterns of vegetation formations present, equally are observed differences in the Oriental region due to the deforestation and vegetation formations with dominance of herbals, as are the wetlands; the analysis intra seasons show results according with the features of the vegetation as the season climate and finally the NDVI corroborate the remainder observations made.
