The study area was the main campus of Embrapa Eastern Amazon, comprising 2706,48 ha located the peryphery of Belém, Pará, Brazil. In order to elaborate a zoning for the ocupation and use of this area, available data and informations of the interest were stored using the geoprocessing system SGI/INPE. The information about land use was obtained through TM/Landsat data of 1995, processed in a SITIM digital image analyser, with use of enhancement and classification techniques, backed by ground truthing. After the storage of the relevant informations in SGI, the zoning was mainly done based on potential use, considering physical and chemical properties of the soil, edaphic limitations and actual land use. Thus information was generated about the land use capacity and recommendations for the six use zones. The information obtained is of great importance as a basis for future administrative action in the study area. From the environmental aspect, the allocation of significant forested areas as conservation units, will contribute to protect a rich biological heritage, essential for the maintenance of environmental quality in the region of Belém.
