Resumo: This article aims to analyze the variations in precipitation, as well as the spatial dynamics of land use and coverage in Tucuruí, southeastern state of Pará, from 1980 to 2015. For this, data from meteorological stations of the National Institute were used. Of Meteorology (INMET) and the National Water Agency (ANA) for the study of precipitation in the municipality, Mann-Kendall and Sen’s Slope tests were used, for the 95% significance level. To understand the changes in land cover in the study area, the linear mixture model in Landsat-TM 3, 5 and 8 segmented images was used, for multitemporal analysis of the land cover classes identified in the municipality. The results indicated that there were no trends in the series of annual precipitation totals (1980 to 2015). However, there were significant variations in the interannual rainfall regime, with an average annual rainfall of 2431.6mm. The data indicated seasonality characterized by two distinct seasons: less rainy, between the months of June to November; and the other more rainy, between the months of December to May. The mapping showed different classes of land use in the period studied, however the classes of native vegetation, secondary vegetation, hydrography and exposed soil showed non-linear spatio-temporal variation, however the class of exposed soil showed an increasing behavior since 1980 with beginning of the hydroelectric plant works. Regarding the annual rainfall of the municipality, it is noted that there is no direct relationship with the classes of land use and coverage in the years analyzed.

Para esto, datos de las estaciones meteorológicas del El Instituto Nacional de Meteorología (INMET) y la Agencia Nacional del Agua (ANA) para el estudio de la precipitación en el municipio, se utilizaron las pruebas de pendiente de Mann-Kendall y Sen, para el nivel de significación del 95%. Para comprender los cambios en la cobertura del suelo en el área de estudio, se utilizó el modelo de mezcla lineal en imágenes segmentadas Landsat-TM 3, 5 y 8, para el análisis multitemporal de las clases de cobertura del suelo identificadas en el municipio. Los resultados indicaron que no hubo tendencias en la serie de precipitaciones totales totales (1980 a 2015). Sin embargo, hubo variaciones significativas en el régimen de lluvia interanual, con una precipitación anual promedio de 2431.6 mm. Los datos indicaron estacionalidad caracterizada por dos estaciones distintas: menos lluviosa, entre los meses de junio a noviembre; y el otro más lluvioso, entre los meses de diciembre a mayo. El mapeo mostró diferentes clases de uso de la tierra en el período estudiado, sin embargo, las clases de vegetación nativa, vegetación secundaria, hidrografía y suelo expuesto mostraron una variación espacio-temporal no lineal, sin embargo, la clase de suelo expuesto mostró un comportamiento creciente desde 1980 con el comienzo de las obras de la planta hidroeléctrica. Con respecto a la precipitación anual del municipio, se observa que no existe una relación directa con las clases de uso de la tierra y la cobertura en los años analizados.O objetivo do presente estudo foi analisar as variações da precipitação e a dinâmica espacial do uso e cobertura da terra no município de Tucuruí, Pará, Brasil, no período de 1980 a 2015. Para isso, foram utilizados dados das estações meteorológicas do Instituto Nacional de Meteorologia (INMET) e da Agência Nacional de Águas (ANA). Para o estudo da precipitação no município foram utilizados testes de Mann-Kendall e Sen's Slope com nível de significância de 95%. Para compreender as mudanças da cobertura da terra na área de estudo, utilizou-se o modelo linear de mistura em imagens Landsat-TM 3, 5 e 8 segmentadas, para análise multitemporal das classes da cobertura da terra identificadas no município. Os resultados indicaram que não houve tendências nas séries dos totais anuais de precipitação (1980 a 2015). Porém, constataram-se significativas variações do regime de chuvas interanuais, com precipitação média anual de 2431.6 mm. Os dados indicaram sazonalidade caraterizada por duas estações distintas: (1) menos chuvosa, entre os meses de junho a novembro; e (2) mais chuvosa, entre os meses de dezembro a maio. O mapeamento mostrou diferentes classes de uso da terra no período estudado, no entanto, as classes da vegetação nativa, vegetação secundária, hidrografia e solo exposto apresentaram variação espaço-temporal não linear. Contudo, a classe do solo exposto exibiu um comportamento crescente desde 1980, com o início das obras da usina hidrelétrica. Em relação à precipitação anual do município, nota-se que não há relação direta com as classes do uso e cobertura da terra nos anos analisados.Research, Society and Development2020-03-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/272610.33448/rsd-v9i3.2726Research, Society and Development; Vol. 9 No. 3; e186932726Research, Society and Development; Vol. 9 Núm. 3; e186932726Research, Society and Development; v. 9 n. 3; e1869327262525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/2726/2071Copyright (c) 2019 luiza de Nazaré Almeida Lopes, Bruna Roberta Pereira Lira, Luiza Carla Girard Mendes Teixeira, Letícia dos Santos Costa, Adriana Albuquerque do Nascimento Sousainfo:eu-repo/semantics/openAccessLopes, luiza de Nazaré AlmeidaLira, Bruna Roberta PereiraTeixeira, Luiza Carla Girard MendesCosta, Letícia dos SantosSousa, Adriana Albuquerque do Nascimento2020-08-20T18:07:57Zoai:ojs.pkp.sfu.ca:article/2726Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:12.357549Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
