| contents | Analysis of the physical-chemical spatial variation of surfacial materials of the Gloria Watershed - Uberlândia-MG Fabiana Cristina dos Santos Silvio Carlos Rodrigues Geografía Social Surface Geochemistry Hillslope Geomorphology Physical and chemical attributes The distribution of surface materials in the Cerrado environment has intrinsic characteristics which are related to topographic positioning, slope shape and water runoff. All these aspects are associated with climatic seasonality typical of this environment. In this way this work aims to investigate the physical and chemical attributes of the surface materials concerned with the geomorphological characteristics influenced by their spatial variability which plays a predominant role in the quality of these ecosystems. The study area is a hydrographic basin located in the county of Uberlândia in the southeast region of the Triângulo Mineiro. The methodology was based on the analysis of the physical, chemical and mapping of some parameters. We analyzed: texture, apparently density, total porosity, organic matter, CEC, V, H + Al, pH, K +, hypsometry and use and coverage. In addition to three maps containing the percentages of clay, silt and sand for the elaboration of the exploratory map and its peripherals of the hydrographic basin. About 80% of the basin is occupied by agriculture and anthropogenic action. The prognostic analysis correlated the physical-chemical attributes subjectively because it is a study based on probabilities considering the available knowledge about each attribute in the national literature. The analysis of the superficial materials added to the mapped attributes offers to the researchers important information endowed with great geographic value, be it in the scope of the geomorphology, or in what refers to the studies of the physical environment integrated to the sectors of planning and environmental management. 2019 artículo científico 0103-1570 https://www.redalyc.org/articulo.oa?id=321363062021 https://www.redalyc.org/journal/3213/321363062021/ https://www.redalyc.org/journal/3213/321363062021/html/ https://www.redalyc.org/journal/3213/321363062021/321363062021.epub https://www.redalyc.org/journal/3213/321363062021/movil 10.14393/SN-v31n1-2019-45624 en http://www.redalyc.org/revista.oa?id=3213 Sociedade & Natureza application/pdf Universidade Federal de Uberlândia Sociedade & Natureza (Brasil) Vol.31 |
