Caracterização dos solos e suscetibilidade à erosão e movimentos de massa no município de Contagem (MG)

Abstract

The disordered urban occupation in Brazil, since the 1950s, has promoted the construction of housing and urban infrastructure in areas where the environmental characteristics (geology, climate, relief, hydrography, and soils) were not properly assessed. Combined with vegetation removal, this pattern of occupation favors the onset and intensification of erosive processes and mass movements, as observed in the municipality of Contagem, Minas Gerais, located in the Metropolitan Region of Belo Horizonte.This study investigated the morphological, chemical, biological, physical, and micromorphological characteristics of five soil profiles located in Morro dos Cabritos (2), Vila Feliz (2), and Vila Epa (1). The methodological procedures included a literature review, production of cartographic materials, laboratory analyses, and fieldwork.The results indicate that the analyzed soils belong to the classes Nitossolos Vermelhos, Nitossolos Háplicos, and Cambissolos Háplicos, and that all five profiles show high susceptibility to erosive processes and mass movements.
