MAPPING THE USE AND OCCUPATION OF THE SOIL OF THE RIBEIRÃO FORQUILHA HYDROGRAPHIC MICRO-BASIN - GOIANÉSIA - GO

Abstract

DUE TO THE LARGE AND RAPID EXPANSION OF URBAN ENVIRONMENTS AND ANTHROPOGENIC ACTION ON THE ENVIRONMENT, IT HAS MODIFIED THE HYDROGRAPHIC BASINS, WHICH TOGETHER WITH THE UNDUE USE OF THE SOIL SUFFER DEGRADATION OF THE NATURAL RESOURCES, ALTERATION IN THE MICROCLIMATE, IN THE FOREST COMPOSITION AND INCREASE OF THE SOLAR RADIATION. IN ORDER TO IMPROVE THE USE OF SOILS AND WATER RESOURCES, MANAGEMENT PLANS ARE NECESSARY, WHICH SPECIFY THE USE AND OCCUPATION OF AREAS SUCH AS AGRICULTURE, FORESTRY, URBANIZATION, ROAD CONSTRUCTION AND RESERVE AREAS. INFORMATION ON LANDSCAPE MODIFICATIONS. THUS, THE PRESENT WORK WAS DEVELOPED IN THE WATERSHED OF RIBEIR�O FORQUILHA IN GOIAN�SIA-GOI�S, IN ORDER TO IDENTIFY THE DIFFERENT USES OF THE SOIL OF THE REGION. DATA WERE USED TO OBTAIN THE POLYGON OF THE BASIN OF THE CARTOGRAPHIC BASE OF THE STATE SYSTEM OF GEOINFORMATION - SIEG, DATA FROM THE NATIONAL INSTITUTE OF SPACE RESEARCH (INPE), FOR THE MONTHS OF SEPTEMBER / 2018 AND MARCH / 2019, USING THE SATELLITE LANDSAT-8 OLI. AS A RESULT, IT WAS POSSIBLE TO MAP SIX CLASSES, AGRICULTURE, EXPOSED SOIL, HYDROGRAPHY, NATIVE VEGETATION, PASTURE AND URBAN AREA, BEING NOTICEABLE THE DECREASE OF AGRICULTURE AND THE INCREASE OF EXPOSED SOIL, HYDROGRAPHY, AND PASTURE BETWEEN THE PERIODS ANALYZED, NATIVE AND URBAN AREA REMAINED STABLE.
