The use and occupation of soil should be planned in a rational way to avoid negative environmental impacts on natural resources, particularly in areas environmentally protected by law. This study aimed to evaluate quality attributes of soil in permanent preservation areas of a Ribeirão do Gama Watershed, Distrito Federal, Brazil, to verify the influence of anthropic use. The physical, chemical and biological attributes of Histosol quality were assessed in five areas of diversified use and soil occupation: three areas under cultivation (vegetables, eucalyptus and cassava) and two preserved areas (native pasture and gallery forest). Soil samples were collected in 0-10 and 10-20 cm depth. The data obtained for physical, chemical and biological analysis of the soils were statistically evaluated using the Sisvar 4.6 software. The results obtained showed the influence of different uses and soil occupation in relation to the attributes of soil quality. The adopted management in these areas was considered the main factor of change in the physical, chemical and biological attributes, highlighting the compaction of soils under native vegetation and decrease of organic matter in the soils under cultivated systems.
