| Abstract | A microrregião do Sudeste Paraense constitui hoje uma das áreas críticas de desflorestamento na Amazônia, fruto das grandes transformações socioeconômicas que tem atravessado. Neste trabalho é avaliada espacialmente a dinâmica da cobertura vegetal e uso da terra nos Projetos de Assentamentos Agroextrativista Praialta e Piranheira, Lago Azul e São Francisco. Para isso, imagens TM/Landsat de 1984, 1988, 1992, 1996 e 2000 foram analisadas considerando a classificação supervisionada por regiões de imagens fração (vegetação, solo e sombra), geradas a partir de modelo linear de mistura espectral. Verificou-se que a redução das áreas de floresta primária está associada aos períodos de ampliação das atividades agropecuárias, cuja intensidade é variável com o projeto de assentamento e o período analisado. As pastagens representam o padrão dominante do uso da terra, cujos incrementos em área chegam, por vezes, a duplicar entre anos consecutivos. Para a dinâmica da paisagem, os maiores percentuais de estabilidade ocorreram principalmente para as classes Floresta Primária e Capoeira Alta. As maiores taxas de conversão entre classes ocorreram para unidades de pastagem, em especial para a classe Pasto Sujo. Os processos de antropização, ocorridos nas áreas de estudo, apresentaram trajetórias distintas, fruto das particularidades do fluxo de migração e de estratégias de distribuição de terras. The southeastern region of Pará, Brazil, constitutes today one of the critical areas of deforestation in Amazonian region, due to the great socioeconomic transformations that have occurred. In this context, the present work evaluates the spatial dynamics of the land cover and land use in the Agroextrativista Praialta and Piranheira, Lago Azul and São Francisco settlement projects. For this, Landsat/TM images from 1984, 1988, 1992, 1996, and 2000 were analyzed considering the supervised classification by regions of fraction images (vegetation, soil, and shade), generated by the Linear Spectral Mixing Model. It was verified that the reduction of primary forest areas is associated with the intensification periods of agricultural and cattle raising activities, with variable intensity according to different settlement projects and the analyzed time periods. Pasture represents the dominant pattern of local land use, increasing in area, sometimes, doubling in consecutive years. For the dynamics of the landscape, the higher percentage of stability occurred for the classes Floresta Primária (Primary Forest) and Capoeira Alta. Higher percentage of conversion to pasture, especially Pasto Sujo (Weedy Pasture), were observed for all the classes mapped. The antropization processes, which occurred in the study areas, have shown distinct trajectories due to the particularities of the migration flow and the strategies of land distribution. |
