Resumo: | Due to the intended development from the landscape dynamics, and the construction of the Belo Monte Hydroelectric Plant, the urban space of Altamira has undergone major transformations in land cover. Therefore, this study aimed to classify and quantify the changes suffered in land use and cover in the urban micro-region of Altamira in the years 2010 and 2018. In the methodology, the online platform MapBiomas was used to classify and quantify the classes of use and coverage from the earth. The values of the samples were measured by the statistical calculator and the field calculator of the QGis 3.4.13 software. The software was used for qualitative and quantitative analyzes and for the generation of the final product (land use and land cover maps). The results showed that in 2010, the area occupied by forest formation extended for 23,631 km², while in 2018 it covered 26,081 km². It appears that urban infrastructure has increased considerably (71%). An important characteristic observed is the appearance of a new class in 2018, referring to the planting of annual and perennial crops, which can be associated with the new activities practiced, resulting from the population increase, and expansion of agricultural activity in the region. Therefore, the class that has undergone the greatest change in the central region of Altamira is that of urban infrastructure. It is possible to verify that the presence of new constructions such as the Transamazônica Highway and the Belo Monte hydroelectric power plant, caused a great change in the use and occupation of the region's soil, mainly regarding the urban fabric of the locality. |

Por lo tanto, este estudio tuvo como objetivo clasificar y cuantificar los cambios sufridos en el uso y la cobertura del suelo en la micro región urbana de Altamira en los años 2010 y 2018. En la metodología, la plataforma en línea MapBiomas se utilizó para clasificar y cuantificar las clases de uso y cobertura de la tierra. Los valores de las muestras fueron medidos por la calculadora estadística y la calculadora de campo del software QGis 3.4.13. El software se utilizó para análisis cualitativos y cuantitativos y para la generación del producto final (mapas de uso y cobertura de la tierra). Los resultados mostraron que en 2010, el área ocupada por la formación forestal se extendió por 23,631 km², en 2018 cubrió 26,081 km². Parece que la infraestructura urbana ha aumentado considerablemente (71%). Una característica importante observada es la aparición de una nueva clase en 2018, que se refiere a la siembra de cultivos anuales y perennes, que pueden asociarse con las nuevas actividades practicadas, como resultado del aumento de la población y la expansión de la actividad agrícola en la región. Por lo tanto, la clase que ha experimentado el mayor cambio en la región central de Altamira es la infraestructura urbana. Es posible verificar que la presencia de nuevas construcciones, como la Carretera Transamazônica y la central hidroeléctrica de Belo Monte, causó un gran cambio en el uso y la ocupación del suelo de la región, principalmente en relación con el tejido urbano de la localidad.Em virtude do desenvolvimento intencionado a partir da dinâmica da paisagem, e pela construção da Usina Hidrelétrica de Belo Monte, o espaço urbano de Altamira sofreu grandes transformações na cobertura do solo. Diante disso, este trabalho objetivou classificar e quantificar as alterações sofridas no uso e cobertura do solo na microrregião urbana de Altamira nos anos de 2010 e 2018. Na metodologia, utilizou-se a plataforma online MapBiomas para classificação e quantificação das classes de uso e cobertura da terra. Os valores das amostras foram medidos pela calculadora estatística e pela calculadora de campo do software QGis 3.4.13. O software foi utilizado para as análises qualitativas e quantitativas e para geração do produto final (mapas de uso e cobertura do solo). Os resultados demonstraram que em 2010, a área ocupada por formação florestal se estendia por 23.631 km², já em 2018 abrangeu 26.081 km². Verifica-se que a infraestrutura urbana aumentou consideravelmente (71%). Uma característica importante observada é o aparecimento de uma nova classe no ano de 2018, referente ao plantio de culturas anuais e perenes, o que pode ser associado às novas atividades praticadas, decorrentes do aumento populacional, e expansão da atividade agrícola na região. Portanto, a classe que sofreu maior modificação na região central de Altamira é a de infraestrutura urbana. É possível constatar que a presença de novas construções como a Rodovia Transamazônica e a Usina hidrelétrica de Belo Monte, provocaram uma grande alteração no uso e ocupação do solo da região, principalmente quanto à malha urbana da localidade.Research, Society and Development2020-07-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/548810.33448/rsd-v9i8.5488Research, Society and Development; Vol. 9 No. 8; e303985488Research, Society and Development; Vol. 9 Núm. 8; e303985488Research, Society and Development; v. 9 n. 8; e3039854882525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/5488/4834Copyright (c) 2020 Atila Fonseca Carvalho Silva, Merilene do Socorro Silva Costa, Matheus Gabriel Lopes Botelho, Layse Gomes Furtado, Gundisalvo Piratoba Moralesinfo:eu-repo/semantics/openAccessSilva, Atila Fonseca CarvalhoCosta, Merilene do Socorro SilvaBotelho, Matheus Gabriel LopesFurtado, Layse GomesBatista, Vanessa de AlmeidaCarneiro, Carla Renata de OliveiraMorales, Gundisalvo Piratoba2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/5488Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:28:59.658414Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
