Geoinformação na análise da ocupação de Áreas de Preservação Permanente no município de Salinópolis, região nordeste do Estado do Pará.

Abstract

The use of geoinformation as an instrument for the representation of spatially referenced data from the geographic space makes it possible to converge different scientific areas for the study of environmental and urban phenomena, and an example of quantification is the mapping of areas of occupation in Permanent Preservation Areas, located in the municipality. Salinópolis-Pará, which are places with environmental damage. The identification and evaluation of these degradation processes are necessary elements to assist in the decisions related to the protective measures directed to these areas, especially in urban areas. This study aimed to evaluate using geoinformation, together with the remote sensing technique to identify the impacts and environmental damage in areas of permanent preservation, caused by human occupation irregularly in the perimeter of the beach. Torch to Atalaia beach in the city of Salinópolis in 2019. Damage identification was performed by analyzing the study area through geoinformation, remote sensing, literature and satellite imagery. The damages were quantified and expressed in maps regarding the classes of permanent preservation areas, extension of the urban / anthropized area and limits of the research area, interactivity of urbanized / anthropized areas and the preservation areas, growth vector, and the minimization measures. Proposed impacts, based on the literature. The degrading actions identified are of different natures and affect the surrounding fauna, flora and population, the environment itself, and the assessment of the damage caused by areas of irregular occupation in these sensitive locations, allowing to understand more precisely the current situation of the existing degradation in the permanent preservation areas of such municipality.
