%X In Acre state change in vegetation occurs primarily by the conversion of forest areas into pastures. It is essential to understand the process of occupation of the landscape. This study aimed to analyze the fragmentation forest dynamics through the use of remote sensing in the vicinity of the city of Rio Branco, Acre, between 1990 to 2010. In the environment of ArcGIS 10.0 software was created to mask reverse deforestation for the years 1990, 1995, 2000, 2005 and 2010, for which they were generated landscape metrics for the classes of fragment size, very small (<5ha), small (5-10ha), medium (10-100ha) and large (> 100ha) using the extension Pacht Analyst 5.1. According to the results of this study we can say that the process of fragmentation, within a radius of 50km from the city of Rio Branco, has been growing over the last twenty years, being most intense between 2005 to 2010. The number of fragmentation was growing by the year 2005 and then decreased due to the extinction process of fragments, which indicate a process of extreme fragmentation. The number of fragments is related to the distance between the nearest neighbors - MNN, the smaller the number of fragments greater the MNN.
