Summary: The agroforestry systems (SAF) are an important strategy of land use, directed to the environment services, in special, to the carbon storage for the biomass. This paper presents activities developed with objective of aboveground biomass estimation (AGB) and the carbon storage (CS), existing in SAF in the Tomé-Açu, Pará, Brazil. The agroforestry data had been gotten by carried through inventory in 57 parcels show of 10x10 m. A tax of 1.424 was inventoried plants/ha, with DAP2,5 cm, pertaining the 29 families and 54 species. Considering it inherent joined variability to the structural and species information, the SAF had been divided in four classes (SAF 1, SAF 2, SAF 3 and SAF 4). For the estimate of the AGB, the indirect method, based was used in allometric equations. The AGB of the SAF was 89,10 Mgha-1 and CS was 43,21 MgCha-1 (2,83 for SAF 1; 18,85 for SAF 2; 36,58 for SAF 3 and 114,58 for SAF 4). The esteem values of CS for each class of SAF had been correlated the four vegetation index (Ratio Vegetation Index ? RS 5:3, Normalized Difference Vegetation Index ? ND 5:7, Transformed Soil Adjusted Vegetation Index 2 ?TSAVI 2 and Perpendicular Vegetation Index 3 ? PVI 3), having significant correlation with this index, indicating the possibility of the use of these pointers in the survey and the monitoring of the carbon in the region.
