EVOLUÇÃO ESPAÇO-TEMPORAL DO USO E COBERTURA DA TERRA NA BACIA DO RIO PURAQUEQUARA (MANAUS-AM)

Abstract

The aim of this work was to perform an analysis of spatiotemporal evolution, in 2005, 2010 and 2016, to use and cover the surface of the Puraquequara River basin, Manaus (AM). Data were obtained from the National Institute for Space Research (INPE) and the Brazilian Institute of Geography and Statistics (IBGE). The cartographic data processing was performed in the Geographic Information System (GIS) environment.  For class mapping, we used an Unsupervised Classification that is done through automatic class processing. The calculation of the area of each of the classes was performed with the aid of the geometry calculation algorithm.The results show that there is a predominance of tropical vegetation class (78.78%), but on the right bank, an exposed soil class (11.23%) and urban patch (1.23%) continue to advance over vegetation areas. native and secondary. Therefore, the attention of the inspection agencies is more necessary, especially for delimitation of the Permanent Protection Area (APP) of streams that flow into the Puraquequara River.
