Análise integrada da paisagem no contexto geomorfológico da Bacia Hidrográfica do Córrego Ibó - MT

Abstract

The present research approaches the integrated analysis of the landscape within the geomorphological context, understanding the need to know and understand the types and forms of relief units, the processes, vulnerabilities and potentialities from the geosystems that integrate them. In the context of the transformations imposed on the different landscape units of Mato Grosso, it is important the science perspective that seeks to improve the guidelines regarding the adequate use and / or occupation of soil and water resources, aiming at future actions. The present theme seeks to carry out an integrated study of the landscape, aiming to understand the dynamics of the relief unit of the Guimarães Plateau and the Interplanáltica Depression of Rondonópolis. In order to do so, we opted for the analysis through the delimitation of the Ibó Stream Basin (BHCI), understanding basin as an important system that can lead to the understanding and clarification of issues related to the geomorphological context, being these responsible for active processes in the sculpture of the terrestrial landscape. The study area is located northwest of the morphostructure of the Paraná Sedimentary Basin, and is part of the municipalities of Mato Grosso do Juscimeira and Santo Antônio de Leverger, located southeast of the capital Mato Grosso Cuiabá. It has its sources in the Guimarães Plateau and in the Interplanáltica Depression of Rondonópolis in the São Lourenço river, one of the tributaries of the Paraguay river, incorporated to the Cerrado and Pantanal biome. The climatic conditions of this area correspond to the type of Tropical Continental climate, with alternation of humid and dry periods. The methodological procedures have a systemic approach, based on the triad: desk surveys, field campaigns and use of Geographic Information Systems (GIS), which enabled, through the geoprocessing tool, the elaboration of thematic maps and evidenced, among other aspects , the characteristics of location, slope, climate, drainage, hypsommetry, geomorphology, pedology, use and occupation of the area in question. The research also seeks to recognize anomalies in relation to the "spontaneity" of the organization of the drainage system, such as the presence of elbows and alignments of drainage headwaters in the geomorphological evolution of the landscape, and the relationships of this evolution with the geographical distribution of soil variables, declivity, climate, use and occupation and their respective degrees of vulnerability, potentiality and possible conflicts of use among the geomorphological compartments of the BHCI.
