Applicazione dell’analisi tridimensionale negli studi di Ecologia del paesaggio

Abstract

Topography and terrain morphology play a key role in landscape structure and functionality. Landscape ecology modelling based on patch-corridor-matrix usually analyzes the area of study as a plane surface. However, this assumption could be critically far from reality, especially in mountainous areas, and lead to significant mistakes in calculation. Different areas of study were analyzed using both classical and more recent indices. Calculation was performed using a bi-dimensional terrain model and a three-dimensional model in which length and surface area values were much closer to real world values. Results were confronted to understand the different sensitivity of various analysis tools to errors introduced with the use of a planar model which cannot perfectly represent a three-dimensional landscape.
