RESUMO

The objective of the research was to make temporal and spatial analysis of land use, in Pirapó-RS, through the use of geotechnologies. The methodology was basically divided into 5 steps: in the first step, diagnoses of land use were made considering the years 1975, 1991 and 2005; in the second step, the land use was monitored taking into consideration the last 30 years; in the third step, an evaluation of the potential land use was made; in the fourth step, the conflict areas of potential land use and the land use in 2005 were monitored; and, in the last step, these results were spatialized and quantified through the signature process. In the first step, Remote Sensing was used, and, in the other ones, Geoprocessing was used. The results demonstrate that a great change happened in the last 30 years considering the land use in the area of study, and that there are some land uses more intense than the recommended use. These factors can contribute to soil deterioration in few years.
