2MAPPING AND QUANTITATION OF PHYTOPHYSIONOMIES IN A FLOODEDAREA OF LOWER TAQUARI RIVERABSTRACT: The study area is the flooding plain of the lower course of the Taquari River,in the Pantanal of Mato Grosso do Sul State Since 1974 this area has been presenting largerannual periods of flood causing changes in the local landscape. This work aims to makemaps and to quantify the different vegetation physionomies of the area, in two periods:1966, representing the drought period, and 1995, representing the period of full water. Thestudy area was defined based on satellite Landsat-TM images and field information. Thequantification of the area was accomplished in the system of geographical information(SIG). For the survey of vegetation cover, black and white aerial photos of 1966 were usedin the scale of 1:60,000, with the interpretation restored to the 1:100,000 scale. SatelliteLandsat-TM images 1995 for were in the 1:100,000 scale. The study area was quantified as11,149,55 km 2 . In 1966, they were identified, initially as 72 vegetation classes and in 1995,50 classes, later on joined by 40 and 33 classes respectively. Eighteen vegetation maps inthe 1:100,000 scale, related to topographical maps, were filed in digital format, at EmbrapaPantanal.
