| الوصف: | The multitemporal analysis of land cover and use within the context of studies of watersheds is a tool for gathering information and understanding socio-environmental dynamics. This study aims to analyze the transformations that occurred in the landscape of the Urussanga River watershed (BHRU), intermediate region of Criciúma, Santa Catarina, Brazil, in three dates: 1986, 2005 and 2020. The thematic classification used the method of regions, the images used derive from the LANDSAT 5 and 8 satellite, the software Qgis, ArcGis 10.3 and IDRISI Selva were used in the digital processing of the images. In the thematic mapping, eight classes of land cover and use were defined. As an instrument to understand the anthropic pressure exerted in the basin, the Anthropic Transformation Index (ITA) was used. The results showed, within the analyzed period of 35 years, that the Urban Spot class had an expansion of 4% and Agriculture presented a slight increase of 0.19%, showing that the agricultural frontiers in the basin are consolidated. The Arboreal and Shrub Vegetation class was the one that had the greatest reduction, as it represented 40.04% in 1986, and 37.13% in 2020, a reduction of 3%, which corresponds to a suppression of 20 km² in the analyzed period. The Mineral Extraction and Dunes classes reduced by an average of 0.50%, the Pasture and Undergrowth classes remained with coverage without significant changes. The ITA calculated based on the mapping of land use and land cover presented a regular classification as a general result for the BHRU, with the greatest pressure exerted on the basin derived from the Urban class, Tree and Shrub Vegetation, and Agriculture. The results obtained in this research may serve as subsidy for future projects of planning and sustainable integrated territorial management of the geographical space within the basin. ; El análisis multitemporal de la cobertura y uso del suelo en el contexto de los estudios de cuencas hidrográficas es una herramienta para el levantamiento de información y la ... |
