RESUMO

The human being aims for dominating the environmental system since the emergence of it on Earth s surface. Its way of appropriation of the space resulted in various impacts levels along its history. In order that there is a sustainable use of this space, practices of territorial management policies are indispensable. Nowadays, the territorial management as a disciplining mechanism of human actions in the environment is assisted by the environmental zoning. The municipality of Saltinho is located in the central region of Sao Paulo State, Brazil. Despite being in a region that has a long history of occupation, has become only municipality in 1991, which previously constituted themselves into district of the city of Piracicaba. The present work aims to undertake a geo-environmental study of the municipality of Environmental Zoning Saltinho (SP) in order to pointing out the environmental impacts caused by human exploration and may serve as a subsidy for a better territorial planning for this municipality. The methodological approach was based on the Theory of General Systems and the proposed Mateo Rodriguez, Silva and Cavalcanti (2004), which conducts an integrated analysis of the components and anthropic natural that subsidizes the division of geo-environmental units and environmental zoning. When combined, the physical characteristics of the municipality and the intense agricultural use create a high environmental scenario of fragility. This suggests the necessity of precaution regarding the use of the land to avoid problems concerning the increase of pluvial erosive processes, such as erosion and silting which already are occurring at the study area. It was possible determine 13 geo environmental units in Saltinho through the combined analysis of natural and social components. As a basic criterion for defining and mapping of these units was considered watersheds, since these singularize areas with similar characteristics of landscape elements. These units have been grouped into three classes: top, slope and valley bottom. From the characterization of geoenvironmental units, the Environmental Zoning was defined, in other words, the ability to land use. The appropriated land uses for the top and slopes permit more varied uses, such as annual crops, urban use, pastures, cultivation of sugar cane, forest and reforestation while using measures for the conservation of soil and respecting the physical characteristics of units and the legislation . Finally, the valley bottom units are areas of permanent preservation, where the forest is the unique appropriate land use
