摘要：This study shows a application of remote sensing techniques for the evaluation of conversion from forest to pasture in the State of Rondonia, Brazil. The main objective of this study was to establish a pasture chronossequence for the analysis of the soil fertility dynamic by using multitemporal Landsat Thematic Mapper data over the State of Rond.nia, in order to optimize the study site sampling in the field. The multitemporal classificaton of shade fraction image derived from spectral mixture analysiswas employed to identify the age of pasture. Using this approach, land cover change between 1987 and 1997 was divided into six age classes , including forest as a control for analysis of the dynamic of the soil fertility
