| description | The Pantanal Park Roads, composed of the state roads MS-184 and MS-228, are located northwest of Mato Grosso do Sul, in
the Paraguay River Basin, crossing the Pantanal, whose plains are susceptible to the natural inundation pulse. Despite their cultural,
ecological, landscape and tourist importance, there are lack studies that would guide the proper planning and management of the
land use and occupation of the region. Thus, the objective of this work was to apply the geoprocessing technique of map algebra,
based on the concept of Ecodynamics, and with the inclusion of a new thematic chart: the flood area, which represents this dynamic
characteristic of the region, for obtaining of natural and environmental vulnerability charts, the latter is distinguished by considering
anthropic interventions on landscape units. To do this, among other procedures, the photointerpretation of satellite images was applied
to update the vectors of the RADAMBRASIL charts from the scale of 1:1,000,000 to 1:250,000, bringing minimal representativeness
of the relevant regional characteristics, as well as the application of the proposed technique. The results obtained are the maps of natural
and environmental vulnerability to erosive processes, and the EPP are both natural and environmentally predominant with moderately
stable/vulnerable areas with a tendency to be moderately vulnerable, and, any changes that occur in the landscape unit, can elevate its
status to vulnerable to erosive processes, increasing the risk of soil loss. |
