Análise temporal do uso e ocupação do solo do município de Dois Vizinhos – PR utilizando imagens Landsat

Abstract

The need for studies on land use land cover has become increasingly importante for the planning of municipalities, enabling a regional view of both urban and rural environments, as these are places where more dynamic processes often occur in the landscape. With this in mind, the aim of this study was to map land use and land cover in the municipality of Dois Vizinhos - PR, for the years 1990, 2000, 2010 and 2020, using supervised classification to obtain the quantitative area for the following classes: Agriculture, urban area, water bodies, forests, pastures and exposed soil. The percentage obtained indicated a predominance of agriculture in all the periods studied, as well as a considerable increase in forest areas over the last three decades. Conversely, the exposed soil class showed a significant reduction as the urban area expanded. The data on the area of water bodies, in turn, remained close to the IBGE and MapBiomas estimates. The areas of forest remnants and planted forest increased by 1,503.15 ha in the period studied, as a result of the efforts and measures to protect native vegetation in recent decades.
