摘要：
This study analyzed spatial and temporal land use changes in the Middle Paraguay River Interbasin-MT, Brazil using Landsat images from 1991, 2001 and 2011. Images were geo-referenced, classified and processed using Spring software, and thematic classes were edited and quantified using ArcGis software. Seven map classes were identified, and native vegetation, pasture and sugarcane were the most significant ones. The results showed changes in all classes during the past 20 years, primarily a 22.89% decrease of native vegetation, a 58.42% increase in pasture and 490.26% increase of sugarcane monoculture. We verified land use conflicts, mostly in riparian areas, which may negatively influence Interbasin and, consequently, Pantanal conservation in the State of Mato Grosso, Brazil.
