Dinâmica de uso e cobertura da Bacia do Rio Água Azul, em Rondon do Pará- PA

The objective of this work was to analyze the dynamics of anthropic activity in the Hydrographic Basin Rio Água Azul in Rondon do Pará- PA, through remote sensing and Geoprocessing techniques, In the mapping of land use and coverage and of conflicts and between land use and the Areas of Permanent Protection (APP’s). Used TM-Landsat 5 image of 1986 and 2001, and used OLI/TIRS-Landsat 8 imagem of 2015. Supervised classification was made with maximum likelihood statistical method and then post classification in Classedit. The classes used in the study were of dense vegetation, secondary vegetation, ground without coverage and agriculture. The delimitation of the APP’s was carried out through the generation of the buffer zone (buffer) from the regular bed of water courses. For analysis of the dynamics of the use it used the tool intersect do Arcgis 10.1 For intersection between classes. The Basin has lost its dense vegetation (about 33%), the APP’s are at odds with Código Florestal and Most of the dense vegetation that existed in 1986 is ground without coverage It concluded that the Basin has been degraded over the past 29 years and the APP’s of the river basin Rio Água Azul Had Had changes of coverage on the sides of the rivers.
