The use of satellite images has been very effective for monitoring the dynamics of the land use and occupation over time. For this purpose , the change detection techniques have been strong allies. These techniques have multiple complexities depending on the objective to be achieved. This study aims to evaluate the technique for land use and land cover changing detection in areas affected by the environmental disaster of November 2008 in the region of Morro do Bau, Santa Catarina, Brazil. A total of 04 (four) images from different dates between 1992 and 2009 (post-disaster) were used. The images were processed in vegetation index using bands 7 and 4 in order to minimize atmospheric and radiometric distortions. Shadow mask, construted from the digital terrain model, was developed to avoid false changes caused by shade. It was concluded that the georeferencing must be very accurate in applying these techniques. The vegetation index by using bands 7 and 4and the shadow mask, were effective in minimizing false changes. It showed that the techniques applied are effective to detect changes in areas affected by the disaster.

Este trabalho, realizado em uma area com povoamento de Pinus taeda, teve por objetivo simular e mapear a influencia do valor de impacto das atividades florestais na fragilidade potencial. Variaveis do solo, de declividade do terreno, valor de impacto e de cobertura vegetal foram utilizadas para gerar os mapas. Os resultados expressos pelo modelo adotado mostraram que as areas mais frageis apresentam em sua maioria declividades superiores a 75 % e textura que variam de arenosa a media, e as areas menos frageis apresentam predominantemente relevo plano (ate 3 %) e textura argilosa. Quando simulado o impacto das atividades florestais sobre esse ambiente, verificou-se que na maior parte da area (78 %) todas as atividades florestais podem ser realizadas sem influencia na degradacao do meio ambiente e para algumas areas (11 %) o ambiente foi considerado menos fragil, em razao da presenca de cobertura vegetal.
