- W2336974405 abstract "Resumo: O presente estudo objetivou aplicar álgebra de mapas, por meio de sobreposição booleana na determinação da dinâmica do uso e ocupação do solo, realizado na cidade de Pombal, Paraíba - Brasil. Foram adotados procedimentos de análise espacial utilizando o SIG/SPRING-5.2, duas imagens 2002/2012 foram registradas, filtradas, classificadas e posteriormente cruzadas por inferência booleana. O principal objetivo da pesquisa foi verificar a dinâmica de uso e ocupação do solo no município de Pombal-PB, cruzando imagens de diferentes sensores orbitais e analisando a dinâmica espacial e temporal da paisagem. Após a análise, constatou-se que houve um crescimento das atividades agropecuárias de 20,3 %, e 3,1 % das áreas com Agricultura Irrigada as margens dos rios Piancó e Piranhas. A Caatinga Estépica Arborizada e Florestada avançaram 23,0 % sobre as demais coberturas e uso do solo, além de 3,8 % das áreas sofreram regeneração, portanto, a qualidade da paisagem teve uma sensível piora em termos ambientais, o que foi determinado pelo aumento das áreas com solo exposto degradado e aumento do nível de alterações antrópicas.Modeling of the use of dynamic and land occupation in the municipality of Pombal - PBAbstract: This study aimed to apply map algebra by means of boolean overlap in determining the dynamics of the use and occupation of land, in the city of Pombal, Paraíba – Brazil. Spatial analysis procedures were adopted using the SIG/SPRING-5.2, two images 2002/2012 were recorded, filtered, sorted and then crossed by inference boolean. The main objective of the research was to investigate the dynamics of use and occupation of land in the municipality of Pombal-PB, crossing images from different satellite sensors and analyzing spatial and temporal dynamics of the landscape. After analysis, it was found that there was an increase of agricultural activities 20.3%, and 3.1% of the areas with Irrigated Agriculture margins of Piancó and Piranhas rivers. The Caatinga Steppe Tree and Woodland advanced 23.0% on other types of coverage and land use, as well as 3.8% of the areas have experienced regeneration, thus the landscape quality had a significant worsening in environmental terms, which was determined by increase in exposed areas with degraded soil and increase the level of environmental disruption." @default.
