| Popis: | The coastal zones are important regions by their fragilities and dynamic. The research area is placed near Macau (RN) county and it is known by land petrol exploration. About this view, this research had made maps of the natural and environmental vulnerability from base maps of geology, soils, vegetation, geomorphology and of using and occupation. Analyzing these maps it can diagnostic sensible areas from environmental problems, by allowing recommendation toward best advantage from control and protect activities. The vulnerability map elaboration aims to show the intensity and its distribution, mainly considering the stability related to morphogenesis and pedogenesis. The methodology procedures consists in the logical integration of different available data, and the set of all these information were integrated to make and to store a georeferencing data base into the Arcview ® GIS 3.2 software, permitting a systematic analysis of each element of thematic maps. The maps crossing was based on stability concept of each unit by considering the ecodynamic analysis concept. |
