Resumo: | Soil erosion is a natural phenomenon that has been accelerated by inadequately human activities, resulting in soil degradation and its multiple functions. In this sense, the objective of this research work is to assess the environmental status of the drainage basin of Pequeno river, Paraty Municipality, Rio de Janeiro State, with emphasis on soil erosion. The methodological procedures involved bibliographical and documentary surveys, fieldwork, analysis of soil attributes and thematic mappings. The results show that the relief characteristics contribute to geomorphological processes acceleration and, despite the limitations, soils showed low erodibility. However, changes in vegetation cover and inadequate use and management have an influence on the supply of organic matter into the soil, which may affect its attributes and increase its erodibility over time. |

En este sentido, el objetivo del trabajo es evaluar el estado ambiental de la cuenca hidrográfica del río Pequeno - Paraty / RJ, con énfasis en el problema de la erosión del suelo. Los procedimientos metodológicos incluyeron encuestas bibliográficas y documentales, trabajo de campo, análisis de atributos del suelo y mapeos temáticos. Los resultados muestran que las características de alivio contribuyen a la aceleración de los procesos geomorfológicos y, a pesar de las limitaciones, los suelos mostraron una baja capacidad de erosión. Sin embargo, los cambios en la cubierta vegetal y el uso y manejo inadecuados influyen en el suministro de materia orgánica en el suelo, lo que puede afectar sus atributos y aumentar su erosión con el tiempo.A erosão dos solos é um fenômeno natural que vem se acelerando pelas atividades humanas desenvolvidas de forma inadequada, resultando na degradação dos solos e de suas múltiplas funções. Nesse sentido, o objetivo do trabalho é avaliar o estado ambiental da bacia hidrográfica do rio Pequeno – Paraty/RJ, com destaque para a problemática da erosão dos solos. Os procedimentos metodológicos envolveram levantamentos bibliográficos e documentais, trabalhos de campo, análises de atributos do solo e mapeamentos temáticos. Os resultados apontam que as características do relevo contribuem para a aceleração dos processos geomorfológicos e, apesar das limitações, os solos apresentaram baixa erodibilidade. No entanto, as mudanças na cobertura vegetal e o uso e manejo inadequado têm influência no aporte de matéria orgânica do solo, podendo afetar seus atributos e aumentar sua erodibilidade com o tempo.Universidade Federal do Ceará2021-01-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.geosaberes.ufc.br/geosaberes/article/view/106010.26895/geosaberes.v12i0.1060Geosaberes; Vol 12 (2021); 23 - 43Geosaberes; Vol 12 (2021); 23 - 43Geosaberes; Vol 12 (2021); 23 - 432178-0463reponame:Geosaberesinstname:Universidade Federal do Ceará (UFC)instacron:UFCporhttp://www.geosaberes.ufc.br/geosaberes/article/view/1060/858Copyright (c) 2021 Geosabereshttp://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessSantos, Rafael CarvalhoGuerra, Antonio Jose Teixeira2021-01-13T11:18:22Zoai:geosaberes.www.geosaberes.ufc.br:article/1060Revistahttp://www.geosaberes.ufc.br/geosaberes/PUBhttp://www.geosaberes.ufc.br/geosaberes/oaigeosaberes@ufc.br||jose.z.candido@gmail.com||fabiomoria@yahoo.com.br2178-04632178-0463opendoar:2021-01-13T11:18:22Geosaberes - Universidade Federal do Ceará (UFC)false |
