Análise do Padrão Espacial do Uso e Cobertura do Solo e da Fragmentação e Conectividade da Vegetação no Semiárido do Nordeste Brasileiro: Bacias Dos Rios Taperoá e Alto Paraíba-Pb

Abstract

The Upper Paraiba and Taperoa river basin are located in the semiarid zone of Paraiba State. Much of the delimitation of the semiarid region has Caatinga forests, which, due to its bioclimatic conditions, diversity and endemism, become a singular biome, extending over a surface area of 844,453Km2 IBGE (2010). The objective of this study was to evaluate soil use and cover, spatial pattern of fragmentation and connectivity of the Upper Paraiba and Taperoa basin. The mapping was done from GEOBIA classification of MSI images of Sentinel 2 satellite, and worked on GUIDOS software. The vegetation cover and the water and bioclimatic condition of the surveyed area were used. The results point to a greater presence of caatinga areas in quantity and connectivity in the northwest of Upper Paraiba and in the southwest of Taperoa.
