Abstract

Adjacent patches of different community types interact with each other via the efflux of individuals of component populations, influenced by the size, shape, arrangement and distance of patches. In a spatial micromosaic of two vegetation types, it is reasonable to assume that the intensity of interactions is proportional to the distances between patches (more precisely, to the distribution of distances). In this paper, a special type of distance distribution functions (DDF) is introduced to predict potential interactions between two communities. Each community is characterised by two functions (i. e., comm. A -» comm. Â and comm. Â -> comm. A). The applicability of the new function is presented in the evaluation of a vegetation map.
