Zusammenfassung: | This article aims to analyze the relationship between the advance of sugar cane and the physical characteristics of the northwest Parana's state (Brazil), in 1985 and 2009. The identification of sugar-cane was made from the interpretation of LANDSAT 5 images, through remote sensing techniques. It was mapped 943 square kilometers of sugar-cane in 1985, and 6177 square kilometers for the year 2009. This information was related to the topics of geology, slope, land degradation, soil ability and risk of frost. It was found that the area occupied by sugar-cane increased in all classes, but the culture progressed preferably over areas with greater degradation, with lower agricultural potential and the Caiua Formation (sandstones), at the expense of less degraded areas with better agricultural potential and on other geologic formations, particularly the Serra Geral Formation (basalts). The risk of frost did not appear as controller of the distribution of sugar-cane in this area of study. Keywords: Sugar-Cane, geoprocessing, remote sensing, northwest Parana State. Este trabalho tem por objetivo a analise da relacao entre o avanco da cana-de-acucar e as caracteristicas do meio fisico do noroeste paranaense, nos anos de 1985 e 2009. A identificacao dos lotes de cana-de-acucar foi realizada a partir da interpretacao de imagens Landsat 5, atraves de tecnicas de sensoriamento remoto. Foram mapeados 943 [Km.sup.2] de cana-de-acucar no ano de 1985, e 6.177 [Km.sup.2] no ano de 2009. Estas informacoes foram relacionadas com a geologia, declividade, degradacao de terras, aptidao do solo e risco de geadas. Foi identificado que a area ocupada por cana-de-acucar aumentou em todas as classes, mas o cultivo avancou preferencialmente sobre areas com maior degradacao, com menor aptidao agricola e sobre a Formacao Caiua, em detrimento das areas menos degradadas, com melhor aptidao agricola, e sobre outras formacoes, principalmente a Formacao Serra Geral. O risco de geadas nao se apresentou como controlador da distribuicao dos canaviais nesta area de estudo. Palavras-chave: Cana-de-Acucar, geoprocessamento, sensoriamento remoto, noroeste do Estado do Parana. |
