Descrição

Landscape metrics have been widely developed over the last two decades. One of the major recent developments in landscape metrics analysis was the integration of the third dimension. Topography has an extremely important role in ecosystems function and structure, even though the common analysis in landscape ecology only considers a planimetric surface, which leads to some erroneous results particularly in mountain areas. In this study we tested landscape metrics behaviour in 13 sample areas of 10,000 m2 each in several topographical conditions of Central Alentejo, Portugal. The significance analysis of the results achieved in planimetric and three-dimensional environments is presented.
