Resumo
The process of urbanization directly implies the occupation of the relief, which appropriated
by man inappropriately, alters the natural dynamic balance and causes environmental
impacts. To understand this relationship between society and nature and how it manifests
itself in the urban space, we sought to analyze the occupation of topographic compartments
over time, in which the study of the drainage headwaters of Ribeirão Pirapitinga, located
within an area of urban expansion of the City of Catalão (GO). The objective of this study
was to identify the urban density and the types of occupation of the compartments, with the
temporal analysis of the vegetation aspects, in order to diagnose the environmental
conditions related to the occupation process. The study was based on Tricart's Theory of
Ecodynamics (1977), on the evaluation of the impacts of human intervention on the
ecosystem, providing the classification regarding the degree of instability. Through a
bibliographic survey on the subject, together with field recognition and aerial images, it was
possible to obtain data and maps that showed the dynamics of the processes that
contributed to the negative impacts, some as the silting of the river channels, the increase
of the runoff, alteration in water recharge, deterioration of water quality, among others
related to anthropization
