Abstract

The objective of this study was to analyze the influence of the landscape structure on the vegetation structure and how this influence is affected by investigation scale. The study was carried out in the Agroextractivist Settlement Praialta Piranheira, Nova Ipixuna, Para State, Brazil. We used floristic inventory (vegetation variables) and satellite image (landscape metrics). The sample plots were spatialized in buffers (100, 200, 300 and 500 m of circumference). We observed influence of landscape metrics, especially the amount of forest habitat, on the vegetation structure and the importance to select the most suitable metrics considering the study objective.
