Abstract:

The Cerrado savanna in the center of Brazil is one of the world’s biodiversity hotspots and features a huge diversity of species and habitats. In the last 40 years, more than 50 % of this area has been transformed to gain land for agricultural use, forestry, the growth of cities and infrastructure. As a consequence, habitats are vanishing and the diversity of species is threatened. The main purpose of this thesis is to examine the types of land use which affect the vegetation of the Cerrado near the city Uberlândia in the state of Minas Gerais. In this regard, gathering the types of land use is of importance to determine the degree of naturalness and the degree of hemeroby. These parameters are significant to evaluate the state of landscape. In order to determine the degree of naturalness areas located in a protected area are used as a reference. The used areas show the stage of succession that shows the highest degree of naturalness. This is important to define naturalness. A mapping of the biotope types in the study area along a road from Uberlândia to a protected area is implemented to gather, categorize and evaluate the biotopes. Therefore a key of the mapping was created. The analysis of the data shows that surfaces which are affected by human use do have significant relevance. Natural areas with a high structural diversity are found rarely. Biotope types with a low degree of hemeroby can also be found, but the impact of humans on the progress on landscape is obvious. Even the areas with a higher degree of naturalness are affected by humans, which points out that nowadays landscape has to be seen as cultural landscape.
