Resumo: This study aims at assessing the land use dynamics as wellas its effects in physical soil characteristics and on the soildegradation in Guarapuava/PR. First of all, the landscapemapping (land unit) of Guabiroba catchment was prepared.After that, the main land use in the study area was chosen.Next, it was sought to evaluate some attributes such as landuse dynamics in subsistence agriculture, litter budget overthe soil, soil resistance, bulk density, total porosity and waterinfiltration into the soil in each land unit. Due to land usediversity and well-defined landforms, the catchment areashowed a mosaic pattern with abrupt boundary. In addiction tothis, a wide variability of soil use and physical-hydric behaviorwas observed. As a result, diverse effects on soil degradationwere found.

Para isso, foi realizado preliminarmenteo mapeamento da paisagem da bacia do Rio Guabiroba.Posteriormente foram selecionados os usos da terra maisfreqüentes no âmbito da bacia. Nesses usos foram avaliadasalgumas características biofísicas como dinâmica do uso daterra em agricultura de subsistência, serrapilheira estocada,resistência do solo, densidade aparente, porosidade total einfiltração de água no solo. O uso da terra na área de estudoapresenta um padrão em forma de mosaico (limites abruptos)em decorrência da diversidade de usos, bem como pelos compartimentosgeomorfopedológicos bem definidos. Diante disso,verificou-se ampla variabilidade na dinâmica do uso da terrae das condições físico-hídricas do solo e, por conseguinte,distintos efeitos sobre a degradação do solo.UFPRCNPqThomaz, Edivaldo Lopes2007-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufpr.br/raega/article/view/343910.5380/raega.v13i0.3439RA'E GA Journal - The Geographic Space in Analysis; v. 13 (2007)RAEGA - O Espaço Geográfico em Análise; v. 13 (2007)2177-27381516-413610.5380/raega.v13i0reponame:Ra'e Ga (Online)instname:Universidade Federal do Paraná (UFPR)instacron:UFPRporhttps://revistas.ufpr.br/raega/article/view/3439/9086info:eu-repo/semantics/openAccess2018-10-03T13:20:10Zoai:revistas.ufpr.br:article/3439Revistahttps://revistas.ufpr.br/raegaPUBhttps://revistas.ufpr.br/raega/oai||raega@ufpr.br2177-27382177-2738opendoar:2018-10-03T13:20:10Ra'e Ga (Online) - Universidade Federal do Paraná (UFPR)false
