Landscape morphology metrics for urban areas: analysis of the role of vegetation in the management of the quality of urban environment

This study has the objective to demonstrate the applicability of landscape metric analysis undertaken in fragments of urban land use. More specifically, it focuses in low vegetation cover, arboreal and shrubbery vegetation and their distribution on land use. Differences of vegetation cover in dense urban areas are explained. It also discusses briefly the state-of-the-art Landscape Ecology and landscape metrics. It develops, as an example, a case study in Belo Horizonte, Minas Gerais, Brazil. For this study, it selects the use of the area’s metrics, the relation between area, perimeter, core, and circumscribed circle. From this analysis, this paper proposes the definition of priority areas for conservation, urban parks, free spaces of common land, linear parks and green corridors. It is demonstrated that, in order to design urban landscape, studies of two-dimension landscape representations are still interesting, but should consider the systemic relation between different factors related to shape and land use.
