Resumo: | Soil loss depends on natural and anthropic factors with high spatial and temporal variability, and can be inferred by predictive models such as the Revised Universal Soil Loss Equation (RUSLE). In this sense, the objective of this work is to analyze the spatio-temporal distribution and variation of soil losses in the state of Goiás for the years 1985, 2000 and 2018, based on the application of RUSLE and using the drainage basin as a multiscale unit of analysis. The results generally show that there has been an increase in the average loss of soils in the state between the observed years, with the average in 1985 being 2.4 ton.ha-1.year-1, growing to 10.8 ton.ha-1.year-1 in 2000, and 11.56 ton.ha-1.year-1 in 2018. The hydrographic regions of Tocantins and Paraná presented the highest losses. In addition to the general control of the Cerrado conversion expansion, the state of Goiás presents two spatial soil loss patterns; one in which the control of natural factors predominates, being linked to morphogenetic aspects with a strong influence of the topographic factor; and the other being rain erosivity, spatialized in areas such as the “front” of Cuesta Caiapó, Serra Dourada and Serra dos Pireneus. When associated, these two factors define sensitive areas with the highest soil losses in the state of Goiás. |

Nesse sentido, o objetivo deste trabalho é analisar a distribuição e a variação espaço-temporais das perdas de solo no estado de Goiás para os anos de 1985, 2000 e 2018, a partir da aplicação da EUPS-M, tendo a bacia hidrográfica como unidade de análise multiescalar. Os resultados demonstram que, em geral, há o aumento na perda média de solos no estado entre os anos observados, sendo que, em 1985 a média foi 2,4 ton.ha-1.ano-1, crescendo para 10,8 ton.ha-1.ano-1 no ano de 2000 e 11,56 ton.ha-1.ano-1 em 2018. As regiões hidrográficas do Tocantins e do Paraná são as que apresentam maiores perdas. Para além do controle geral da expansão da conversão dos Cerrados, o estado de Goiás apresenta dois padrões espaciais de perda de solos, um no qual predomina o controle dos fatores naturais, ligados aos aspectos morfogenéticos com forte influência do fator topográfico e o outro da erosividade das chuvas, espacializadas em áreas como o “front” da cuesta Caiapó, a Serra Dourada e a Serra dos Pireneus. Esses dois fatores, quando associados definem áreas sensíveis, com as maiores perdas de solo do estado de Goiás.Universidade Federal de Uberlândia2022-11-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/6603410.14393/SN-v35-2023-66034Sociedade & Natureza; Vol. 35 No. 1 (2023): Sociedade & Natureza; v. 35 n. 1 (2023): 1982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUengporhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/66034/34940https://seer.ufu.br/index.php/sociedadenatureza/article/view/66034/34941Copyright (c) 2022 Lucas Espíndola Rosa, Luís Felipe Soares Cherem, Lionel Siaméhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRosa, Lucas EspíndolaCherem, Luís Felipe SoaresSiamé, Lionel2023-08-25T14:36:00Zoai:ojs.www.seer.ufu.br:article/66034Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2023-08-25T14:36Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
