AbstractThe ecological theory has been developing for many years in trie same conceptual and methodological framework as the general theory of Systems (Hernández, 1991). Ecosystems, as complex systems, are in many cases difficult to study, but much more when they are subjected to human interventions during many centuries. Such is the case of Agrosystems. The agricultural landscape is the expression in space and time of human effort in search for his daily nourishment. But since the landscape is a complex system of relationships, it is necessary to analyse its components so as to understand the past and their processes of development The present trends about landscape knowledge, taking into consideration the ecological and systemic approach are expressed in Hernández and Pastor (1991). We have already talked about the high degree of resemblance that exists between "ecological thought" and "sisternic thought" (Hernández and Pastor, 1989). Now the question is if we can apply the most theoretical question to the realization of a project about the changes which some characteristic systems can suffer. It is a question of giving importance to ways of relationship man-nature and of social interaction which can satisfy basic human needs, but looking for a new balance with the environment at the same time. Therefore we'll talk about agroecosystems. In short, to maintain the ability of production and respect for the environment. To apply the knowledge of systems science to our study subject means that agroecosystems will be explained by means of some variables which is important to determine.
