Resumo
The analysis of land use and land cover is fundamental for the strategic
planning to the conservation and management of a watershed. This study
aimed to analyze the landscape of the catchment area of João Leite River,
located in the State of Goiás, to the Northwest of the city of Goiânia, the state
capital, using Geographic Information System (GIS) and Remote Sensing to
prepare an environmental assessment of that watershed. A multi-temporal
analysis using images obtained by the TM sensor installed in the Landsat-5
satellite, from 1985 to 2011 showed, in the catchment area of the João Leite
River, a decrease of 7.4 % in the native vegetation area. Considering the
municipalities integrating the basin, Anápolis was where most deforestation
occurred in areas with native vegetation (11.1%). These results are relevant
to institutions dealing with environmental management, showing that
deforestation is directly related to the environmental quality of the basin,
which has as one of its uses the urban water supply of municipalities located
in the Metropolitan Region of Goiânia.
