Résumé:
The study aims, through the elaboration of a geoambiental map, include drainage
information, topography, geology, soils, geomorphology, surface features, land use,
permanent preservation areas and conflicting using areas, watershed for the creek
Val Paraiso - PB, to help in developing strategies and actions that may trigger a
future process of environmental planning and management. The theoretical and
methodological approach in this study was based on a holistic view, looking at the
theory of a synthesis of multicomponent systems in an integrated geoambiental
analysis. The watershed Val Paradise belongs to sub-basin of the Rio do Peixe and
comprises an area of 7,962.97 ha and is located in the northwest portion of the
Paraíba state, northeastern semiarid. This region shows serious cases of
environmental degradation associated with the fragile natural and anthropogenic.
The map was prepared by geoambiental Geographical Information System IDRISI
32, developed by Clark University (1994), topographic based maps, the image sensor
Quickbird dated 2004, auxiliary maps and field work. The watershed is composed of
sedimentary and rocks crystalline, with soil that, in most, have problems with
drainage, high levels of clay and salts. The topography varies from mild to undulating
wavy, showing problems with different uses and environmental deterioration. About
50% of the watershed area is conducive for agriculture and grazing, but the region
suffers from shortage of water and native vegetation. An analysis of the attributes of
the physical environment and integration of these seven were established
geoambientais, with the presentation of its weaknesses and potential locations.
These units were represented by a Geoambiental Map.
