A General Indicator of Soil Quality (GISQ) has been proposed by Velasquez et al. (2007) which combines a set of subindicators. These subindicators may also be considered as indicators of the performance of different ecosystem services (ES) such as soil structure and nutrient cycling. This study aimed to evaluate the impact of different land-use systems on soil quality in a Natural Reserve of South Brazil. Variables associated with soil diversity, fertility, physical properties and aggregate morphology were measured for each system. The highest GISQ average value was calcu-lated for the Forest (0.80), while this system also had the highest values for macrofauna, chemical and physical subindicators. PCA analysis showed a significant separation (p&lt0.001) of the Soybean crop from the others systems based on the lowest subindicators values. The GISQ reflected the pro-vision of soil ES, showing that better soil quality produces more ES. The methodology used can be applied extensively and allows monitoring of land-use changes through time. It could therefore gui-de the implementation of soil restoration technologies.  asoil quality  aCalidad del suelo  aIndicador  aIndicator  aLand use system  aQualidade do solo  aServicio ecosistémico  aSistema de uso da terra1 aVELASQUEZ, E.1 aSANTOS, A.1 aBARTZ, M.
