STRUCTURE AND GEOECOLOGICAL FRAGMENTATION OF THE RIVER LANDSCAPE IN THE LOWER XINGU RIVER - CENTRAL-EASTERN AMAZON

Abstract

The geoecological analysis seeks to subsidize the planning of the uses and occupation of the landscape in accordance with its limits and potentialities. The study area is river landscape located downstream of the Hydroelectric of Belo Monte on the lower Xingu River, which promotes modifications in the regional geoecological context. In order to understand the geoecological structure of the fluvial landscape in the lower Xingu River, including the analysis of the metrics and fragments that compose it's units. The landscape was analyzed through a systemic and holistic study of data produced in field activities, bibliographical and using remote sensing and geoprocessing techniques. The understanding of the interrelations between the components of the landscape allowed the identification and characterization of the fluvial landscape units. The transgression of the Atlantic Ocean over the Amazon River makes it possible to increase and reduce daily, and may increase or decrease seasonally the Xingu River.
