The present work aims to represent the dynamics of geosystems from the integrated analysis of sites (geoforms) and states (land use and land cover), based on the application of principles coming from the geosystems theory. Studies such as this one allow the promotion of corrective or preventive interventions for the conservation of existing natural resources, through the use of geotechnologies as decision support tools in environmental management. The study area consists of a 525ha tract in the municipality of Triunfo (PE), an area of exceptional soil and climate conditions in the semi-arid region of Pernambuco (Northeast Brazil). To this end, an integrated interpretation of high-resolution aerial images from different years was carried out to determine changes in land use and land cover. In parallel, landscape sites were mapped, defined by relief forms and surface materials. Finally, a landscape unit map was constructed by integrating the site and state maps. The techniques employed proved to be relatively uncomplicated and accessible procedures for rapid assessment of landscape units.
