Resumo: Considering the complexity of macrohabitats in the Pantanal and their relationship with hydrological variations, the study aimed to compare the phytophysiognomy variation and the temporal behavior of the Normalized Difference Vegetation Index (NDVI) considering the flood pulse of the Northern Pantanal (15º42’27”/16º48’52”S and 55º2’2”/56º0’17”W). We used SIG Arcgis 10.2.2 and MODIS images (MOD13Q) for mapping of leaf mass variation (2010 to 2012). For the total area (7,553.28 square kilometers) there was an increase of twice the high vigor vegetation from the dry to the rainy season. The highest values recorded for NDVI in flood and high waters corroborate the statement that the flood correlates with the increase in vegetation vigor, which becomes denser in the Forested Savannah (43%) and the Semideciduous Seasonal Alluvial Forest (35%) and smaller in the Grassy-Woody Savannah and Park (22%). In the low waters, the vegetation decreases its leaf mass and the Grassy-Woody Savannah and Park Savannah classes occupy a wide area of the plain (81%), in contrast to Forested Savannah (13%) and Semideciduous Seasonal Alluvial Forest (7%) show a reduction in leaf cover. The NDVI were efficient in the analysis and interpretation of leaf variation in a region where the flood creates diversified vegetation landscapes.

Se utilizó SIG Arcgis 10.2.2. e imágenes MODIS (MOD13Q) para mapear la variación de masa foliar (2010 a 2012). Sobre un área total de 7.553,28 kilómetros cuadrados el incremento fue del doble de la vegetación de alto vigor durante el período seco a lluvioso. Los mayores valores para NDVI en la crecida y aguas altas corroboran con la afirmación de que la inundación se correlaciona con el crecimiento del vigor de vegetación, que se torna más densa en la Sabana Floresta (43%) y Floresta Estacional Semidecidual Aluvial (35%) y menor en la Sabana Gramíneo-Leñosa y Parque (22%). Contrariamente aguas abajo la vegetación disminuye su masa foliar y las clases Sabana Gramínea-Leñosa y Sabana Parque ocupan un área de la planicie (81%), en compensación a la Sabana Floresta (13%) y Floresta Estacional Semidecidual Aluvial (6%) que sufrió una reducción en su cobertura foliar. Los datos de NDVI se muestran eficientes en el análisis e interpretación de variación foliar de la vegetación, en una región donde la dinámica de inundación crea paisajes vegetales diversificados.Considerando a complexidade de macrohabitats no Pantanal e suas relações com as variações hidrológicas, o objetivo deste estudo foi comparar a variação fitofisionômica e o comportamento temporal do Índice de Vegetação por Diferença Normalizada (NDVI) considerando o pulso de inundação do Pantanal Norte (15º42’27”/16º48’52”S e 55º2’2”/56º0’17”O). Foi utilizado SIG Arcgis 10.2.2. e imagens MODIS (MOD13Q) para mapeamento da variação da massa foliar (2010 a 2012). Para a área total (7.553,28 quilômetros quadrados) houve aumento do dobro de vegetação de alto vigor do período seco para o chuvoso. Os maiores valores na enchente e águas altas corroboram com a afirmação de que a inundação se correlaciona com o acréscimo do vigor de vegetação, que se torna mais densa na Savana Florestada (43%) e Floresta Estacional Semidecidual Aluvial (35%) e menor na Savana Gramíneo - Lenhosa e Parque (22%). Durante as águas baixas a vegetação diminui sua massa foliar e as classes Savana Gramínea – Lenhosa e Savana Parque ocupam ampla área da planície (81%), em compensação a Savana Florestada (13%) e Floresta Estacional Semidecidual Aluvial (6%) sofreram redução em sua cobertura foliar. O NDVI foi eficiente para a interpretação da variação foliar, numa região onde a dinâmica de inundação cria paisagens vegetacionais diversificadas.Universidade Estadual de Londrina2020-01-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado pelos paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/3715310.5433/2447-1747.2020v29n1p175GEOGRAFIA (Londrina); v. 29 n. 1 (2020); 175 - 1902447-1747reponame:Geografia (Londrina)instname:Universidade Estadual de Londrina (UEL)instacron:UELporhttps://ojs.uel.br/revistas/uel/index.php/geografia/article/view/37153/26743Copyright (c) 2020 GEOGRAFIA (Londrina)http://creativecommons.org/licenses/by-nc/4.0info:eu-repo/semantics/openAccessAlves, Gustavo Benedito MedeirosLoverde-Oliveira, Simoni Maria2022-09-20T15:57:59Zoai:ojs.pkp.sfu.ca:article/37153Revistahttps://www.uel.br/revistas/uel/index.php/geografiaPUBhttps://www.uel.br/revistas/uel/index.php/geografia/oairevista.geografia.uel@gmail.com||marcar@uel.br||laudi@uel.br2447-17470102-3888opendoar:2022-09-20T15:57:59Geografia (Londrina) - Universidade Estadual de Londrina (UEL)false
