Environmental planning studies are important tools used for the conservation of natural landscapes. The objective of this study was to evaluate the eco-dynamic stability and environmental fragility of the Cabaçal river basin, Mato Grosso State. The methodology of empirical analysis from the environmental fragility proposed by ROSS (1994) was applied, using geo-technologies for mapping the index of relief dissection, soils, land use/land vegetation cover, and climate. Approximately 60% of the area from the basin under study presents unstable eco-dynamic units. The Rio dos Bugres subbasin is the unit with the greatest landscape instability (74.39%). The Rio Branco subbasin has the highest areal percentage of class Strong fragility (20.38%). It is concluded that most of the extension of the Cabaçal River basin presents a high fragility and unstable eco-dynamic units which can compromise the environment in this importante unit of the Upper Paraguay Basin and the Pantanal biome
