Relação entre NDVI e florística em fragmentos de floresta estacional decidual no Vale do Paranã, Goiás

Abstract

The objective of this paper was to evaluate the relationship between NDVI and the patterns of the dominant species in three fragments of seasonally deciduous forest (SDF) in the Parana Valley in Goias State, Brazil. Landsat 7 ETM+ images from the year 2001 were used. The study showed a relation between NDVI and floristic patterns during the dry and rainy seasons for the three fragments studied. Exclusive species showed greater influence in the spectral response measured by NDVI than did the total species. The results confirmed the three fragments as SDF showing that even within the same physiognomy there were small phenological variations.
