Dinâmica do Uso e Cobertura do Solo em Áreas Queimadas de Municípios na Amazônia Brasileira

The disordered occupation in the Amazon, the population growth due the National Integration Plan and the lackof new techniques and technologies diffusion for crops management, economically accessible and lessaggressiveness to the environment, resulted in the suppression of the natural forest in approximately 25% of thetotal area Of the Amazon. A factor associated with this suppression, due to its economic viability and localculture, the fire, is used for the conversion of forests to agricultural areas and the maintenance of previouslyestablished crops. In order to study this context, the present paper had as objective to identify the classes of landuse and cover associated with the fire spots detected by satellites, also indicating burn recurrence areas for themunicipalities of Santa Maria das Barreiras - PA, Colniza-MT And Porto Velho - RO.The results indicate that inthe period from 2008 to 2014, 67% of the areas associated with the fire spots presented "Low" occurrence,associated mainly with the "Pasture" classes. There was an average loss of forest area of 7.2% over lowrecurrence areas, while in high recurrence areas there was an average loss of 22.5%
