Item Avaliação da ocupação e uso da terra nas bacias hidrográficas da região metropolitana de Goiânia/GO (2010)(Denis Castilho, 2014-03-30) Silva, Marcos Vinícius Alexandre da; Ferreira, Nilson ClementinoThis study aimed the exploratory analyzes on the land use and land cover in Goiânia Metropolitan Region, contemplating the watershed, which are now being considered in land management. Were prepared mappings of the landscape elements and of permanent preservation areas according the environmental legislation, by using images obtained by the sensor LISS III coupled in the satellite Resourcesat-1, and also elevation data obtained by the Shuttle Radar Topographic Mission - SRTM. We verified that 19% of the surface in the Metropolitan Region has been urbanized, and the remaining 81% are in rural areas. We found watersheds with up to 73.65% of its surface occupied by urban areas and basins with 41.18% of its area covered by native vegetation. The regional portion that has impacted watersheds, having their permanent preservation areas occupied mostly by agriculture, pasture or urban area is the northwest, mainly due the conurbation process in the municipalities of Goiânia, Trindade and Goianira. The results obtained can be used for land management and regional planning, which may indicate areas that need special attention of the government to ensure regional sustainability.
