Mapeamento da fragilidade potencial no município de Céu Azul – PR: Subsídio para o zoneamento urbano e rural

Abstract

The exploratory use of the environment together with the lack of environmental planning entails several changes in the natural environment, therefore, the mapping of potential environmental fragility is used to avoid and/or minimize environmental impacts. Based on these characteristics, the present study aims at the mapping of spring areas and environmental fragility in the city of Céu Azul, located in the western region of Paraná. The springs were identified and listed using the software “Google Earth Pro” and the thematic maps were elaborated with the aid of some softwares like “Google Earth Pro” for land use and land cover map, “Global Mapper” for the pedological map and “Qgis” for the slope map. This maps served as a basis for the development of the map of potential environmental fragility, later, it was associated at the urban and agricultural area in order to identify the classes of fragility present in each one. It was possible to identify that of the 71 springs only 9 are all protected, this represent only 12,67% of the total. Related with the fragility, it was obtained that the majority of the urban area is present in areas of weak and very weak fragility and a small percentage in the areas of medium and strong fragility. The agricultural areas are present in all classes of fragility, between very weak to very strong, therefore, requiring the adoption of conservation techniques and corrective measures. Therefore, this study contributed to the urban and rural zoning of the city of Céu Azul – PR.
