Dinâmica espacial de uso e ocupação do solo urbano no município de Breu Branco-PA

Abstract

Breu Branco is a municipality in the state of Pará, located in the microregion of Lake Tucuruí. Over the years, the municipality experienced an accelerated population growth, a consequence of the migration of people from other municipalities of Pará and the northeast region of Brazil in search of work and housing near the works. The spatial growth has a strong relationship with the implementation phases of the Tucuruí HPP. In addition to the population factor, three other factors were important for the Breu Branco spatial growth: the price of land, the topography of the expansion area and the lack of environmental protection policies the municipality. In this work, we used cartographic tools and remote sensing for the construction of maps in three periods 1996, 2006 and 2016. The results obtained show new spatial dynamics, such as the duplication of the urban area, saturation of the projected nucleus of the city towards the north, conversion of forest and preservation areas (APP) into occupations, real estate concentration and speculation about new areas, from the point of view. population view an increase of 58% of the population in twenty years.
