【 摘 要 】

What direction would landscape composition evolve if human activities were minimal?. An approach to probable changes in current landscape in the Spanish Central Pyrenees . This paper compares the current landscape composition, in the Aragon Subordán Basin (Central Pyrenees), a potential one charecterized by lov^ human intervention. To evaluate these changes a land uses map was generated, using Landsat satellite images, as well as a potential vegetation map. Several transitions in land uses are evaluated and the different landscape compositions are analyzed using the diversity, dominance and equitability index. The results show that current landscape presenst higher biodiversity and lower dominance indexes than the potential landscape.
