The present work aims to, classify the different classes of land use and vegetation cover in the Grande stream basin, and quantify the state of preservation of the vegetation around the springs of the Grande stream, which belongs to the Ponte de Pedra basin (Rondonópolis-MT). The classification of land use was realized on ArcGIS 10.5 and the diagnostic of APPs preservation level from headspring, it gave as of generated map of land use and applied the Kappa index. The temporary cultivation (58%), discovered area (16%) and forest (15%) predominated among the land uses classes and vegetal cover. Between the 35 headspring, 23 are excellent in relation to vegetation on around, three very good, three good, three reasonable, one bad, and two terrible, the farming is that who more advanced over at APPs of headspring. The localization and quantification of land uses on headspring is a strong tool on planning and management in these areas.
