英文摘要	It is essential the use of GIS for mapping of geo-environmental unitsand remote sensing to analyze of coverage of land, mainly in areas susceptible Desertification (ASD), such as the municipalities of Castelo do Piaui and Juazeiro do Piaui. Thus, this study aimed to identify the geo-environmental units present in the municipalities of Castelo do Piaui and Juazeiro do Piaui and analyze, through the images of the satellite Landsat 5 TM and remote sensing, the state of the vegetation and use of land at such plants. Five geo-environmental units have been identified, based on the Digital Elevation Models (DEM) and GIS techniques namely: i) Surface Pedimentada Dissected in Hills/Hills and Tabular Forms of Juazeiro do Piaui; ii) Landings Structural river Poti Basin; iii) Valley River Basin Poti; iv) Surface Pedimentada Dissected in Hills/Hills and Forms of Castel, do Piaui Tabular; v) Edges Cuestiformes Preserved interior of the Sedimentary Basin of Maranhao/Piaui. The dynamics of the use and coverage of land showed that such relief units decreased agricultural activities and increased shrub savanna and tree savanna. They were thus broaden knowledge about the environmental dynamics of the study area with a view to territorial planning of it.
