Análise multitemporal de longo prazo da cobertura vegetal do Parque das Dunas de Natal/RN

Abstract

This work aims the long term (decadal) multitemporal analysis of the vegetation cover of the Parque das Dunas de Natal since its establishment as a Permanent Preservation Area (PPA) in 1977. It is intended to evaluate if there was a reduction in vegetation cover, besides verification extension of urban expansion on its area. The analysis of the vegetate cover indicator is based on the fact that vegetation is one of the most important instruments for the Park's equilibrium, since it provides dune fixation, decreased runoff, increased infiltration, improved quality of the infiltrated water, is food and shelter for the fauna, gives substrate to the evolution of the soil and brings thermal comfort by providing better of microclimate. The study also makes an analysis of the effectiveness of PPA protection legal instruments in order to ascertain whether legal guardianship has been effective in its role of protecting the environment. Finally, a long-term multitemporal analysis, performed with digital image processing, with remote sensing, expect to find a reduction in vegetation and increasing urban sprawl into the Park boundaries, especially in the bordering areas, in them where there are greater anthropological pressures of urban growth and densification.
