Dissertação (Mestrado em Geografia) - Universidade Federal de Goiás, Catalão, 2019.http://repositorio.ufcat.edu.br/tede/handle/tede/10991The 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 anthropizationAttribution-NonCommercial-NoDerivatives 4.0 InternationalOcupação urbanaCabeceira de drenagemRelevoImpactos ambientaisUrban occupationDrainage headReliefEnvironmental impactsCIENCIAS HUMANAS::GEOGRAFIADissertação
