Área de proteção ambiental do Vacacaí-Mirim/RS: uma proposta para sua delimitação espacial

Abstract

The problematic of this master s degree dissertation involves the definition of a space for the Area of Enviromental Protection Vacacaí-Mirim, not yet established. The general objective consists on presenting a proposal to delimitate the area, in order to redefine the perimeter proposed by Nascimento (2010), incorporating features not included in the Nascimento s work. The specific objectives are: classify the study area into landscape units; establish the perimeter redefinition; elaborate a synthesis map showing the actual situation of the space, pointing out aspects to be considered in a posterior territorial planning. Through both a deductive scientific method of research and a systemic approach, one tried to accomplish the objectives of this study through the concept of landscape, making it a geographic contribution to environment studies. The results showed that the more conserved Mata Atlântica remaining can be found in the Rebordo do Planalto landscape unit. Such unit predominates in the new proposed delimitation for the Area of Enviromental Protection, which presents a more suitable form for conservation, if compared to Nascimento s (2012) proposal, diminishing the border effect on the vegetation, increasing the coverage of UC, totalizing approximately 88 km².
