             abstract = "The fragmentation of forest habitats in urban areas has aroused 
                         increasing interest in recent years according to the growing 
                         environmental problems. The fragmentation of theses ecosystems is 
                         caused, in general, by the pressure of housing, agriculture and 
                         industry, causing losses in biodiversity and problems of soil 
                         degradation in the border areas of theses remnants. The 
                         establishment of indicators of soil degradation becomes essential 
                         for the implementation of conservation and reclamation. This study 
                         analyzes physical and chemical characteristics of soil under 
                         different forms of vegetation in the forest surrounding the 
                         Quilombo Forest, located in Campinas/SP Brazil, and examines the 
                         possibility of using these indices as indicators of environmental 
                         degradation in urban remnants. The parameters analyzed were: 
                         specific weight natural (\γn), specific weight of solids 
                         (\γs) Ca, P, K, Mg, pH, organic matter, H + Al, Sum of Base 
                         (SB) Percent Base Saturation (V%), Cation Exchange Capacity (CEC). 
                         The study shows that in general the different forms of land used 
                         in the study area significantly changed (or according to) the 
                         physical aspects of soil The porosity and voids of the soil stood 
                         out as the best indicators of soil physical degradation in the 
                         layer 0-20 cm deep. In relation to chemical indices, the soil 
                         under the cultivation of cane sugar had a significantly higher pH, 
                         K, Ca, Mg and sum of bases. The areas of forest showed higher 
                         levels of phosphorus, organic matter and CEC, indicating the 
                         importance of maintaining vegetation and replacement for the 
                         cycling of organic matter.",
