Abstract

The thesis belongs to the concpetual foreground of territorial policies and planning practices for biodiversity conservation, focusing in the ecological network as a model useful in landscape planning. Ecological networks concept, attractive for its semplicity and intelligibility, leaves a real sense of imprecision and impracticability that motivate the need for a deep re-thinking of its foundamenal paradigms. This is the target of the research. The aim is to define a new GIS framework for planning capable to integrate in the latest advances in the theoretical landscape ecology, for a refinement of ecological network model towards a best integration in planning. Categorical representation of landscapes has heavily influenced the dominant paradigm (patch-matrix model) recognized meaningful in describing ecologicl processes. The inadequacy of this paradimg is the foundamental hypothesis of this research. The recognition of a complex system of hidden assumptions is demonstrated to be the real cause of failure for the ecologcal network concept and model for landscape planning. Furthermore a new theoretical development in landscape ecology (the landscape gradient model) was recognized as the new potential tool to redraw a unexplored relational domain between planning and ecology based on a process-based point of view. Thanks to recent development in GIS techniques a methodological proposal, aiming to demonstrate the skills of this new approach in facing planning problems, is presented.
