Diversità e interfacce nell'analisi zonale della vegetazione

Abstract

Diversities and interfaces in the zonal analysis of vegetation. – The attention is called to the growing complexity of ecological and phytogeo-graphical problems emerging from the examination of the diversities of the vegetal landscape. The trend towards typologies, zonations both in the altitudinal sense and latitudinal sense has produced very useful schemes and frameworks which are fundamental references. But problems become more and more extensive and critical in the areas of transition between these types and these zones. These areas, which are particularly fragile, being as they are the centre of delicate balancing processes, are expanding – mostly for anthropical action – to such extent as to become wider than the typical zones codified by usual schemes. Therefore it is required a more intense research even for exigencies of conservation of the land, vegetation and values of human interest.
