摘要

This study aimed at the multitemporal mapping of Land Use Land Cover use in the municipality of Manoel Urbano - AC, using Landsat TM images between 1987 and 2007. Procedures for processing, interpretation, classification, map generation and quality assessment of products generated were carried out using the ERDAS / IMAGINE 8.5 software. The main results showed that in the images of 1987 and 2007 were mapped four land use/land cover classes: Ombrophilous Forest with Bamboo which covered an area of 692,153 ha (65.07%) and 700,765 ha (65,88%), followed by Dense Ombrophilous Forest with 343,359 ha (32.28%) and 326,207 ha (30,67%), deforestation with 23.013 ha (2.16%) and 31,426 ha (2.95%) and water bodies with 5,175 ha (0.49%) and 5,302 ha (0,50%), respectively. It was concluded that along the evaluated twenty years, deforestation took place slowly compared to other regions in the Amazon, especially when assessing on total deforested area.
