Abstract
This paper aims at a clarification of the concept of ‘Landscape Complexity’ (LC). It is concluded that: a) not all landscapes can be considered as ‘complex systems’ according to the criteria of Complex Systems Theory; b) there are three types of LC: structural, functional/hierarchic, and qualitative, hence it is more appropriate to talk about ‘landscape complexities’ than about a single LC, c) the hypercube can be an appropriate conceptual model to represent the interrelationships among these types of LC and their changes over time.
