The objective of this study was to analyze the structural changes of the landscape in the River Basin of the Aguapeí River/MT, in the years 1991 and 2011, through the use of geotechnologies and metrics. This study is based on a categorical approach, which classes discrete belonging to the vegetation cover and land use were identified and mapped by means of geotechnologies and characterized quantitatively by indices of Landscape Ecology, adopting the conceptual model of "stain-corridor-matrix'. It was found that the landscape of the study area form a mosaic, showing an array consisting of savanna (Cerrado), with several spots of livestock, and an area of influence urban, being that the latter class did not exist in 1991, and the corridor formed by alluvial forest in River Basin of the Aguapeí. The data showed a decrease in the area occupied by savanna vegetation and the growth of the agricultural activity in the period analyzed. In case of this pattern is maintained, indicates that in the next 20 years may be the matrix of the basin be constituted by agricultural activity resulting in simplification of ecosystems. Thus, there is a need for regional development policies of Mato Grosso prioritize environmental conservation, which will reflect in land use planning, to improve the permeability of the landscape.
