Uso e cobertura do solo da bacia hidrográfica do Ribeirão Salabra, MS

Abstract

The survey of the use and land cover is important for implementation of agricultural and environmental planning. Thus, this study was to perform the mapping and quantification of current land use in the catchment area of Ribeirao Salobra, MS, aiming to provide support for environmental and agricultural planning. The study area is located in Terenos City, MS, in the vicinity of the Pantanal biome. Images of sensor Thematic Mapper (TM) of Landsat 5 were processed in software SPRING. For this, the processes of geometric correction, segmentation, region extraction, classification, and mapping were achieved, and field work to validate the use classes identified. In the thematic map generated, the classes cerrado, savanna, degraded pasture and pasture have covered approximately 13%, 10%, 35% and 38% of the area, respectively. The predominance of grassland, about 73%, used in livestock farming, was verified. The methodology shows to be satisfactory and capable of supporting the agricultural and environmental planning. Moreover, the gratuity and easy access to data provide further new studies in the basin.
