英文摘要 | The desertification generates and accents the scarcity of vital natural resources for the survival human being, as drinking waters, alone agriculturist and vegetation. Implying in social and economic problems in the affected areas. Recently the remote sensing and the techniques of geoprocessing has been used in diverse areas of the research, mainly in the ambient monitoring of Brazil. For its great territorial extension the application of these tools is of great importance in the country, has seen that if it can thus carry through diagnostic of areas of difficult access by means of transports and in accordance with the secular resolution of the effective satellites can be carried through a monitoring of these areas. The present study it has as objective to analyze the evolution of the process of desertification through the NDVI in the region of the Hinterland of the State of Pernambuco through a secular series of images Landsat Thematic Mapper (TM) that it includes years 1994, 1997 and 2001. It was applied the Surface Energy Balance Algorithm for Land - SEBAL, this algorithm calculated the albedo and the Normalized Difference Vegetation Index for each pixel of the images. It was verified that the characteristic vegetation of the region diminished its area, showing that the analyzed areas meet in process of loss of the vegetation that can lead to the desertification process. |
