Abstract

CORREA, CLAUDIA V.S. et al. Geo-environmental zoning using physiographic compartmentalization: a proposal for supporting sustainable decision-making. An. Acad. Bras. Ciênc. [online]. 2017, vol.89, n.3, pp.1503-1530.  Epub Aug 07, 2017. ISSN 1678-2690.  https://doi.org/10.1590/0001-3765201720160915.

The geo-environmental zoning represents an important strategy in the territorial management. However, it requires a logical and structured procedure. Therefore, an approach using physiographic compartmentalization is proposed and applied as case study in a region covered by the topographic maps of São José dos Campos and Jacareí, Brazil. This region has great geological and geomorphological peculiarities, beyond being a place with large human interventions because of its quickly economic growth. The methodology is based on photointerpretation techniques and remote sensing in GIS environment. As a result, seven geo-environmental zones were obtained from a weighted integration by multicriteria analysis of physiographic units with land-use classes. In conclusion, taking into account potentialities and limitations, the proposed approach can be considered able to support sustainable decision-making, being applicable in other regions.
