RESUMOO trabalho objetivou conhecer o perfil socioeconômico, as principais formas de uso do solo e as alterações no ambiente natural observadas na bacia hidrográfica do Rio Carapá, no município de Colider, Mato Grosso. Realizaram-se visitas in loco e aplicação de questionário composto por nove questões abertas. Foram entrevistados 30 camponeses em 16 diferentes comunidades rurais. Para a delimitação da área de estudo foram utilizadas informações de bases cartográficas com imagens de satélites LandSat (TM5), que refletem a situação da cobertura do solo e a interferência antrópica sobre o sistema natural. Os resultados mostram que a região da bacia hidrográfica e entorno encontra-se com desflorestada e, que para ampliar as áreas de pastagens as Áreas de Preservação Permanente -APP foram suprimidas. Aliados ao problema da ausência da vegetação ciliar e das áreas que seriam reserva legal, o solo e os recursos hídricos estão exposto a diferentes tipos de agentes de degradação. A rede de drenagem possui 234.849 km, sendo a densidade de drenagem considerada baixa com 6,9 m.ha -1. O estudo evidenciou que a região foi colonizada na década de 70 por migrantes vindos da região sul do país, pois há um percentual expressivo de famílias oriundas do Estado do Paraná, que trouxeram em sua bagagem o modelo de produção de uso e ocupação do solo de suas localidades de origem. Palavras-chave: uso do solo; degradação dos recursos hídricos; bacia hidrográfica do Rio Carapá; atividade agropastoril; densidade de drenagem. ABSTRACTThe study aimed to know the socioeconomic profile, the main forms of land use and changes in the natural environment observed in Carapá River Watershed in the city of Colider, Mato Grosso. There were visits on the spot and there was conducting interviews with a questionnaire composed of nine open-ended questions. We interviewed 30 farmers in 16 different rural communities. For the delimitation of the study area were used cartographic information with Landsat satellite images ( TM5 ) , that reflect the situation of the ground cover, as well as human interference on the natural system. The results show that the region of the watershed and its surrounding areas is deforested and, and to extend the grazing areas, the Permanent Preservation Areas (APP) were suppressed . Allied to the problem of lack of riparian vegetation and areas that would be legal reserves, soil and local water resources are exposed to different types of degradation agents. The drainage network has 234,849 km, and the drainage density is considered low with 6.9 m.ha -1. region was colonized in the 70's by migrants from the southern region of the country , as there are a significant percentage of families from the state Paraná , who brought in his luggage the production model of use , which occupy their places of origin. The study showed that the region was settled in the 70's by migrants from the southern region of the country, in view there is a significant percentage of families from the state of Paraná, who brought in their carry the product...
