Dynamique de l'organisation écologique d'un paysage rural du comté de Dundas.

Abstract

The goal of this thesis is to establish if the dynamic model of ecological organization at a distance reflect the same influence or different influences than the ones which acted upon the areas in the vicinity of the city. In order to accomplish this, existing studies of Phipps, Baudry and Burel measuring the ecological organization of a rural landscape in two segments submitted to a low urban pressure (between 1 Km and 10 Km from the city) and high urban pressure (less than 1 Km to the city) will be used. The problem is seen from a landscape point of view, from the organization measured in time and from the variable effect of the urban pressure. With the results of this study, we should be able to complete the picture of the study of the dynamic of the ecological organization of a landscape in view of the distance to the urban center.
