This study aims at analyzing the deforestation evolution correlated to the proposal of a territorial planning implanted by Rondônia Social-Economical and Ecological Zoning – SEEZ – decree number 4.297 signed in July 2002), regulated in 2002. In order to determine theindicators of degradation (deforestation), we opted for the analysis of maps of deforestation elaborated in the years: 1973, 1991 and 1999. We used digital classification of sensor image TM/Landsat (scenes 230/68, 231/67, 231/68, 232/66 e a 232/67, bands – 3, 4 e 5), and digitalized in a Geographic Information System – GIS/SPRING version 4.0 e COREL DRAW-10. The SEEZ/RO establishes three zones: zone – 01, destined mainly to agriculture and cattle raising activities, zone – 02, composed by special areas and zone 03 represented by areas of restricted use (Conservation Unity). The deforestation in Rondônia increased in the period from 1978 to 1999, when the deforested area passed from 420.000 hectares to 5.418.059 hectares, respectively, which corresponds to 23, 71% of the state of Rondônia.
