Considerando que na orla costeira do município de Salvaterra-PA, no trecho que se estende da foz Paracauari à ponta do Tapariuaçu, a dinâmica atual da unidade de baixo platô é marcada pela erosão, relacionada à energia potencial do relevo e à forma de uso e ocupação antrópica dessa unidade; e que a dinâmica das unidades de duna e praia também são determinadas principalmente pelas formas de uso e ocupação antrópica, ligadas à atividades comerciais e turísticas, este trabalho teve como objetivo analisar os indicadores de vulnerabilidade ambiental identificados na orla costeira do município de Salvaterra, no trecho considerado, e classificá-la quanto ao grau de vulnerabilidade ambiental. Esta análise nos possibilitou perceber que a orla de Salvaterra, apresenta alto grau de vulnerabilidade ambiental no setor norte e médio grau de vulnerabilidade ambiental nos setores central e sul.
Palavras-chave: Orla costeira; vulnerabilidade ambiental; uso e ocupação.
Environmental Vulnerability in Coastal Zone of the Municipality of Salvaterra Marajo Island – PA, in Section Between Output Paracauari River and Tapariuaçu Tip
ABSTRACT
Whereas in the coastal municipality of Salvaterra-PA in the stretch that extends from the mouth to the tip of Paracauari Tapariuaçu, the current dynamics of the unit low plateau is marked by erosion, related to the potential energy relief and how to use and human occupation of this unit, and that the dynamics of dune and beach units are also determined mainly by the use forms and the human occupation, related to commercial and tourism activity, this study aimed to analyze the indicators of environmental vulnerability identified in the coastal municipality of Salvaterra, on the section considered, and classify them according to degree of environmental vulnerability. This analysis enabled us to realize that the edge of Salvaterra, a high degree of environmental vulnerability in the northern sector and a medium degree of environmental vulnerability in central and southern sectors.
Keywords: Coastline; environmental vulnerability; use and occupation.
