%X High atmospheric concentrations of global warming gases produced by anthropogenic activities have generated great demand for research about stocks and fluxes of carbon. The study aimed to assess the relationship between the spectral indices (NDVI, PRI e CO2flux) in Botucatu - SP, to find relations of stock and carbon sequestration, in a time series of 30 years. For research, three scenes from different dates were selected; all of these images is of the Landsat-5 TM sensor from orbit / point 220/076. The scenes were chosen in three different years, at the same season. The first chosen scene was the image of the day 12/09/1991, the second chosen scene was of the day 25/10/2001, and the last image chosen was of the day 19/09/2011. The maps of NDVI, PRI and CO2flux showed us a huge variation, when compared temporally. The scene of 2001 possess better performance in carbon sequestration, since it possessed higher values of NDVI, which it is directly proportional to the carbon sequestration. The higher is the value of CO2flux greater amount of the carbon stored, allowing better development conditions for vegetation. A significant increase was observed in the values of CO2 flux for Barra Bonita dam along the temporal analysis, in the same manner as was observed on the image of NDVI. The indices used allowed us to observe the progress of degradation in Barra Bonita dam, representing the behavior of the environment over the years.
