Resumo
O Zoneamento Geoambiental é parte do processo de planejamento de uso da terra, com a definição de áreas territoriais homogêneas, segundo suas características naturais e avaliadas em função de suas potencialidades e limitações, com o propósito de determinar suas necessidades de manejo ou conservação e a sua tolerância às intervenções do homem. Assim, o objetivo desse trabalho é o de delimitar zonas geoambientais na escala 1:100.000 na região compreendida pelas folhas São José dos Campos e Jacareí (SP) a partir da compartimentação fisiográfica (pelo método integrado) e do uso e cobertura da terra, utilizando o método de sobreposição de cartas e da análise multicriterial. A escolha da região como área de estudo decorreu pelas suas peculiaridades geológicas e geomorfológicas, além de se configurar como um local que foi palco de grandes intervenções antrópicas, devido ao seu elevado crescimento econômico. Os procedimentos metodológicos foram a realização da Compartimentação Fisiográfica a partir de técnicas de fotointerpretação em imagens de sensoriamento remoto e o mapeamento de Uso e Cobertura da terra com técnicas de sensoriamento remoto e de geoprocessamento. Foram encontradas no total 19 unidades fisiográficas, distribuídas ao longo da Bacia Sedimentar de Taubaté e no Embasamento Cristalino. O principal tipo de uso ocorrente é a pastagem, que domina cerca de 59,70% da área. O mapa de Zoneamento Geoambiental foi obtido através do método de sobreposição ponderada (análise multi-critério) a partir dos resultados produzidos pela Compartimentação Fisiográfica e Uso e Cobertura da terra, onde foram definidas sete zonas homogêneas segundo as potencialidades e suscetibilidades aos processos do meio físico e à ocupação antrópica, visando auxiliar no planejamento territorial e nas decisões de cunho ambiental
The Zoning Geoenvironmental is part of the process of planning land use, with the definition of homogeneous territorial areas, according to its natural characteristics and evaluated in terms of their potential and limitations, in order to determine their needs for management or conservation and its tolerance to human intervence. The objective of this research is to delineate geoenvironmental areas in scale 1:100.000 of the region comprised by São José dos Campos and Jacarei ( SP ) from the physiographic subdivision ( by integrated method ) and land use and cover mapping using the method of overlapping maps and multicriteria analysis. The choice of the region as an area of study period is due for its geological and geomorphological peculiarities, besides being set up as a place which was the scene of major human interventions, due to its high economic growth. The methodological procedures were the realization of Physiographic Subdivision from photointerpretation techniques in remote sensing imagery and mapping of land use and cover with remote sensing and geoprocessing. 19 physiographic units distributed along the Sedimentary Basin of Taubaté and Basement Complex were found in total. The main type of use is occurring grassland that dominates approximately 59.70 % of the area. Geoenvironmental Zoning was obtained by the method of weighted overlap (multi - criteria analysis) from the results produced by Physiographic Subdivision and land use and cover , where seven homogenous zones were defined according to the potential and susceptibilities to the processes of the physical environment and human occupation, aiming to assist in territorial planning and decisions of an environmental nature
