Resumen
SHIDA, Cláudia Nagako y PIVELLO, Vânia Regina. Physiographic characterization and land use in Luiz Antônio and Santa Rita do Passa Quatro, SP, throughout the use of remote sensing and GIS. Invest. Geog [online]. 2002, n.49, pp.27-42. ISSN 2448-7279.
This study characterizes a region of about 82.655 ha, in Luiz Antônio and Santa Rita do Passa Quatro municipalities, SP, according to its physiography, vegetation and land uses, and identifies homogeneous landscape units which could be used for regional planning; the existence of relationships between the regional physiography and present land uses were verified. Using GIS techniques, homogeneous landscape units were identified according to physiography, land uses and native vegetation. The Chi-squaretest revealed significant associations between land uses and physiography, soil type being the most important one. Six homogeneous landscape units were identified, and in most of them, land uses were adequate according to the physiographic features. Agricultural and silvicultural activities are also present in areas of restricted use, where today's land uses should be replaced by more suitable ones.
