| Resumo | This paper shows results of an experiment that explored the temporal variation of the vegetation index NDVI (Normalized Difference Vegetation Index) of several vegetation covers that occur in the Brazilian Legal Amazon. The value of NDVI obtained from NOAA satellite, has been shown for the estimation of a number of ecosystem variables. such as leaf area index and photosynthetic active absorbed radiation by the canopy, which in turn are essential for the modeling of gases, mass, and energy exchange between the biosphere and the atmosphere, contributing therefore, for the understanding of global change processes. Long-term monitoring (August 1981 to June 1991) of 8 vegetation types (Dense Forest ("Terra Firme" and "Várzeas"), Open Forest ("Terra Firme" and "Várzeas"), Transition Forest , Seasonal Forest ("Caatinga"), and two types of "Cerrado" which occur in the northern part of Brazil (3° N-18°S and 35°W e 74°W) is discussed. For each vegetation type, 10 samples of 3 x 3 pixels centered on the coordinates of selected samples were chosen and monthly composites of NDVI were obtained from GAC ("Global Area Coverage") data. Analyses also involved the yearly composite of NDVI to verify the inter-annual climatic variation. Throughout the analysis of 10 years of data it is clearly noticed the variation on the NDVI due to different satellites, indicating the need for calibration of AVHRR data for multitemporal studies. Seasonally of "Cerrado" and especially of "Caatinga" is outstanding, NDVI values vary from 3 to 4 times for the "Cerrado" and "Caatinga", respectively, in extreme years. Preserved "Cerrado" ("parque") was always distinct from Dense Forest ("Terra Firme") in any season of any year analyzed, however, better distinction is found during the dry season, especially in September. A comparison between normal and El Niño years indicated the influence of this phenomenon on the phenology of the forest vegetation. The phenology of forest covers, except "Caatinga" and "Cerrado" does not vary much throughout the year, however. for El Niño years, as 1983, there is a clear reduction in the NDVI values during the dry season, especially for the Transition Forest. This indicates the importance of multitemporal data for the characterization of forest ecosystems. Dense vegetation covers showed high NDVI values (~ 0.5), "Caatinga" had an average NDVI of ~ 0.35 with large seasonal variation, and "Cerrado" had average NDVI value ~ 0.3 with great seasonal variation but never reaching the "Caatinga" greenness peak (NDVI ~ 0.5). |
