Resumo: | Murundus fields, also known as covoais, are frequent microreliefs in the Cerrado. These are sets of semicircular elevations that protrude from the surface of the land, rounded or oval, with average dimensions of 70 cm in height and 6 m in diameter. They are associated with wetlands and have been impacted by agricultural expansion. The determinants of its regional spatial distribution are still poorly known. This study aimed to identify the natural determinants of its spatial distribution in the Southwest of Goiás, in the Sedimentary Basin of Paraná. All occurrences of murundus fields identified by the project Mapping of Remnant Murundus Fields in the state of Goiás (SEMAD-GO/LAPIG-UFG) were compared with information referring to lithology, geomorphology, NDWI (Normalized Difference Water Index), and SMI (Soil Moisture Index). The indices were obtained from SENTINEL 2-A (MSI) and Landsat 8 (OLI and TIRS) orbital images. It was found that murundus fields preferentially occur in the Alluvial Deposits, Cachoeirinha, Detritic-lateritic Covers, and Serra Geral geological units. Murundus fields predominate under slopes of 0 to 8% (flat to gently undulating relief), and in areas with lower drainage density. The NDWI and the SMI indicated that murundus fields are concentrated on wet surfaces, occurring less frequently in saturated/very wet areas and in moderate humidity, dry, and very dry surfaces. |

Trata-se conjuntos de elevações semicirculares que sobressaem da superfície do terreno, arredondadas ou ovais, com dimensões médias de 70 cm de altura e 6 m de diâmetro. Encontram-se associados a áreas úmidas e vêm sendo impactados pela expansão agropecuária. Os condicionantes de sua distribuição espacial regional são ainda pouco conhecidos. O objetivo deste trabalho foi identificar fatores naturais condicionantes de sua distribuição espacial no SO de Goiás, na Bacia Sedimentar do Paraná. Todas as ocorrências de campos de murundus identificadas pelo projeto Mapeamento dos Remanescentes de Campos de Murundus no Estado de Goiás (SEMAD-GO/LAPIG-UFG) foram comparadas com informações referentes à litologia, à geomorfologia, ao NDWI (Índice de Diferença Normalizada da Água) e ao SMI (Índice de Umidade do Solo). Os índices foram obtidos por imagens orbitais SENTINEL 2-A (MSI) e Landsat 8 (OLI e TIRS). Constatou-se que os campos de murundus ocorrem preferencialmente nas unidades Depósitos Aluvionares, Cachoeirinha, Coberturas Detrito-Lateríticas e Serra Geral. Predominam sob declividades de 0 a 8%, (relevo plano a suave ondulado) e nas áreas de menor densidade de drenagem. O NDWI e o SMI indicaram que os campos de murundus se concentram em superfícies úmidas, ocorrendo com menor frequência em áreas saturadas/muito úmidas e em áreas de umidade moderada, secas e muito secas.Universidade Federal de Uberlândia2023-11-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/6903810.14393/SN-v36-2024-69038Sociedade & Natureza; Vol. 36 No. 1 (2024): Sociedade & NaturezaSociedade & Natureza; v. 36 n. 1 (2024): Sociedade & Natureza1982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUporenghttps://seer.ufu.br/index.php/sociedadenatureza/article/view/69038/37204https://seer.ufu.br/index.php/sociedadenatureza/article/view/69038/37205Copyright (c) 2023 Amanda Morais Malheiro , Veronica Natalia Boeira, Guilherme Taitson Bueno, José Roberto Mantovanihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMalheiro , Amanda MoraisBoeira, Veronica NataliaBueno, Guilherme TaitsonMantovani, José Roberto2024-05-13T15:01:07Zoai:ojs.www.seer.ufu.br:article/69038Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2024-05-13T15:01:07Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
