Fragilidade ambiental no setor norte do município de Juiz de Fora (MG): subsídios da geomorfologia ao planejamento urbano

Abstract

Population growth drives urban sprawl of cities. The geomorphology applied becomes indispensable, as the man appropriates relief to build your house and reproduce life, because there are changes in environmental systems that form the basis on which society projects. The city to be understood as a complex whole, on which there are processes that change the shapes. Also take place changes in ways that alter the processes. Any type of change promoted by urban settlements, however subtle it may be, may cause variations that are perpetuated in time and space, often irreversible and damaging to companies. The main objective of this work is constituted to study the dynamics of geomorphological system for the interpretation of the prism ecodynamic proposed by Tricart (1977). Lens will also determine the environmental fragility from the methodological proposal of Ross (1994), using the concept of Ecodinâmicas units. By establishing the environmental fragility it is possible to assess the areas which may appear more pronounced frames facing instability to the projection of society on the environment. So you can support planning actions that restrict or (re) to target the use and occupation of land in order to prevent or minimize the emergence of the environmental quality problems. The study was applied to an area called North Juiz de Fora Municipality Sector. This sector was selected because it contains different types of land use and vegetation cover, with some natural environments and other man-made urban and rural use. As input were used secondary data result of work in the office and field, for the characterization of key factors: geology, relief (compartmentalization, vertical dissection, slope), soils, land use / land cover and climate.
