Avaliação de um Modelo de Vegetação Potencial para a Região Nordeste com Restrições Hídricas

The present work applies the model of REY to calculate the potential vegetation of the Northeast of Brazil and, thus, to verify if it model identifies the biomes of that region for capacity of field 50 mm, 100 mm and 200 mm. The method used to calculate the rate of Evapotranspiration (ET) is based on the equation of Penman-Monteith. The model also includes fixed parameters and the variables vegetation height and leaf area index (LAI). In general, the model provided a good representation of the biomes of the Northeast of Brazil, mainly the Caatinga and the Atlantic Forest.
