Abstract: | For a sustainable, resource-protecting and participatory land use planning, an easily understandable visualization of geo-scientific factors is important, since only then these data can be accessed by a large group of decision makers and stake holders. The present study aims at supplying this information for the northern periphery of Belo Horizonte, which is under strong pressure of urbanization. In a base step, available geo-scientific data for the study area around the city of Lagoa Santa were collected and checked for consistency. Excursions and field studies supplemented the analysis of literature data. Based on this information, the geological map was updated and the weathering depth and thickness of geological strata estimated. Using a descriptive concept of geology-soil-landscape interrelation, maps of hydrological soil properties were derived. During this process, a detailed analysis of relief structures played an important part. From these geological and pedological base data, several maps of easily interpretable parameters were derived that are relevant for land use planning. Among these are maps showing the intrinsic vulnerability of the aquifer, the distribution of mass resources for construction, areas of high agricultural value and hazard maps with a focus on erosion and pollution of surface water. In total, nearly 90 maps of geo-scientific parameters were derived, among which about one third are aggregated thematic maps that can be directly included into the land use decision process. The rest of the maps display base data regarding relief, geology, hydrology and soil science. The data base of the project and the workflow for the regionalization of the geo-scientific parameters are transparently documented and stored in a Geo-Information-System (GIS). This allows for inclusion of new data into the algorithms and an easy update of the generated thematic maps. |
