CARACTERIZAÇÃO AGROAMBIENTAL DA BACIA HIDROGRÁFICA DO RIO DOCE APOIADA A GEOTECNOLOGIA

Abstract

The geoagroenvironmental study of the hydrographic basins are extremely important to subsidize management and planning for sustainable development. Given this this study aimed to evaluate the agro-environmental characteristics of the watershed of the Doce River in the state of Goiás. Through the QGIS software, the usage map was carried out and land occupation, using mapbiomas image and geographic information system of Goiás, Slope and altimetry using data also from the Information System geographical areas of Goiás and Embrapa. In the northern part of the basin, there was a predominance of agricultural use, mainly of Soybeans (33%), where the highest altitudes are found and the relief is (22.58% and 62571.06ha), while in the southern region, there are lower altitudes and a slightly wavy relief, in these areas pastures predominate, with 23%, the second being increased land use. There is also a trend towards agricultural expansion, in line with the regional bias.
