| Resumo | The feedback mechanisms between climate and vegetation have an important role in the dynamics of the biosphere-atmosphere interaction. In this sense, the knowledge of spatial distribution, temporal dynamics and biophysical characteristics of the vegetation types, are important elements to improve the understanding of how vegetation interacts with the atmosphere. The main objective of this study is to determine the relationship of environmental variables such as precipitation and fire with the patterns of spatial and temporal distribution of the main vegetation type, in the Brazilian tropical savanna. The methodology consists of the spatial and temporal analysis of the following variables: precipitation, density of fire spot and vegetation indices (normalized difference vegetation index-NDVI, enhanced vegetation index-EVI and land surface water index-LSWI) for the years of 2002, 2005 and 2008. The temporal resolution is 23 periods of 16 days each to complete a year and the spatial resolution is 1 km to the vegetation indices and density of fire spots, and 20 km for precipitation. Points randomly distributed along the entire biome were sampled (N=800) to perform statistical analysis. Time series and multivariate analysis techniques were applied to relate the influence of environmental variables (precipitation and fire) with the distribution pattern of 4 vegetation types (forest, savanna with trees, shrubs and herbaceous) in the study area. The results show seasonality in precipitation, density of fire spot and vegetation indices of the vegetation types analyzed along the biome. In general, the analysis show a direct positive relationship between precipitation and leaf biomass production (derived from vegetation indices), and on the other hand, both variables (precipitation and vegetation) show a negative relationship with the density of fire spots. This means that increases in precipitation are related to increases in vegetation cover and decreased in density of fires spots. It was also found high density of fires spot in the dry season in deciduous trees, shrubs and herbaceous which indicates the high removal of CO2 (greenhouse gas) of the land cover to the atmosphere somehow influencing the dynamic equilibrium of this (atmosphere) in the region of the Brazilian tropical savanna. |
