摘要：Deforestation processes in the Brazilian Amazon have attracted a great amount of attention. Colonization incentive policies induced the implementation of rural settlements, without considering the constraints of each region and consequent environmental impacts. This paper analyzes the influence of different architectures of colonization upon landscape fragmentation. Two settlements were selected in Rond.nia: Vale do Anari, where the orthogonal road network is often referred to as a 'fishbone' pattern, and Machadinho d'Oeste, a settlement designed to conform to local topography. Landscape structure indices were calculated, using a LANDSAT TM image from July 1998. The results show distinct fragmentation patterns in Machadinho and Anari . The method, based on landscape ecology and remote sensing techniques, may be useful to evaluate potential environmental impacts resulted from the establishment of colonization projects in the Amazon
