RESUMO

In the context of the current and increasing discussion, on global scale, regarding environmental problematic, the great urban centers show themselves as a primary picture of a very dose relation ship between life quality and degradation of natural resources. The studied area of Anhumas river basin, located on Campinas/SP, fits this perspective. Frequently fluvial impacts allied to committed environmental conditions, show themse1ves directly very dose to the trend spatial-history of basin occupational expansion, thus aggravating a serious social space reality. Pieces of information that show, in a systematic way, the environmental characteristics of such territorial unit, become essential, therefore, besides it s collaboration on local nature-society relationship understanding, acting as the base of the actions that search for effective improvements for the evidenced conditions. Therefore, the main objective of this essay is based on a methodical propose which has the purpose to evaluate the environment quality in different areas on Anhumas basin, demonstrating the influence suffered and at the same time performed by this areas over society. This evaluation will be created by the application of quantitative geoindicators, subdivided on indicators of "State-Pressure-Answer", in a way that integrates the information and condition from different environments. The use of these indicators, in order to quantify the environmental quality, was rea1ized starting at the classification of the "Integrated Physic-Ambient Unit". The mapping of these units will have as main base the geomorphology characteristics of the basin, that had been mapped starting at the overlapping of integrated physical data. Given this, the use of geoprocessing techniques will be essential to reach the proposed objectives
