英文摘要	The degradation of native forest, in dry regions, is expanding due to the exploitation of wood and the conversion of vegetation to different uses. Thus, the objective was to analyze the fragmentation of the landscape in semi-arid areas and the influence of the altitudinal gradient in this process. To do so, the RapidEye images acquired in the year of 2014 were segmented, identified and classified in Forest and Other uses, and also categorical maps were made to be used in the Fragstats software and generate data for analysis of the landscape metrics. The results of the parameters determined that the dry regions have a high amount of fragments smaller than five, demonstrating a high shredding. The Lowland environment is the most affected, due to the greater amount of smaller fragments and the distance between them, this is due to the forest cover of this environment is under pressure being more vulnerable to fragmentation, due to the agricultural cultivation and pasture. On the opposite side is the Plateau environment, in which the Forest class behaves as the matrix of the landscape. Therefore, altitude influences the fragmentation process of native vegetation of semiarid regions, since increasing the altitude also increases the connectivity between the fragments.
