AbstractMutual variations in soil and vegetation pattern characteristics have not received much attention despite their role in the evolution of eco-geomorphic systems. Five landscape metrics of: number of patches, their density, size heterogeneity, shape and dominance were employed for characterizing complementary patterns of soil and vegetation over a wide range of densities. These metrics were calculated for alarge number of modeled patterns, based on a Cellular Automata technique, implementing four different vegetation spread strategies. Based on this data, it was shown that mutual variations in the soil and vegetation metrics allow differentiation between pattern evolution stages such as: perforation, dissection, fragmentation, shrinkage and attrition of one surface type through the spread, expansion and aggregation of the complementary surface type. Such information might be indicative of the hydro-geomorphological processes taking place.
