Cobertura vegetal da região do cerrado : carta da cobertura vegetal

Abstract

Abstract:

This work deals with the mapping of the "cerrado" area, in the 1:1.000.000 scale, with the help of photo interpretations of Landsat images and mosaics of Radar, in black and white, and with the utilization of bibliographies, low-altitude flights, and ground trip.

The result was the recognition and the delimitation of a great number of vegetation formations, some of them typical of the phytophysionomy of the "cerrado": clean field of "cerrado", dirty field, thin "cerrado", "cerrado" "stricto sensu" or dense "cerrado", and "cerradão". Other formations constitute real enclaves joined to conditions which are different of those predominant in the typical area of "cerrados": several forest types, damp "várzeas" vegetations, typical plant associations of the "caatinga" area, mosaics of vegetation essentially in the area of the "pantanal", rupestral vegetation, as well as reforestation areas and those occupied by agriculture activities.
