Dinâmica do uso da terra na área de influência da rodovia Cuiabá-Santarém (BR-163)

The multitemporal monitoring of land use in the Amazon basin, its relationship with the other components of the environment, society and the economy is a critical issue for the development of Brazil. The purpose of this study was to analyze changes in land use in the area of influence of the BR-163 highway in the Cuiabá-Santarém stretch, that is comprising an extension of almost 1,800 km. It was adopted as an area of influence an zone of 100 km around of the BR-163, that provided a study area with approximately 362,975.2 km2. It were used information about land use and ocupation of the TerraClass project for the years 2004, 2010 and 2014 as temporal data source. In addition, land use classes were associated with the presence of Heat, thereby obtaining the effects of burning as a soil-modifying agent. The results showed that the changes in the primary vegetation cover is associated to agriculture and cattle raising, using the burning, to clean the area. It was con-cluded that the activities employed, despite the decrease in some degree of the pace, continue to advance to-wards the area that should be protected in the Amazon.
