Classificação e análise das unidades de paisagem na bacia hidrográfica do Rio Jagui – sub-região de fronteira XIV Cone-Sul, Mato Grosso do Sul

Abstract

The present dissertation consists of the identification, classification and analysis of the Landscape Units (UPS) that compose the Jagui River Basin (BH), in the extreme south of the state of Mato Grosso do Sul. The classification and diagnosis of Ups were elaborated according to the homogeneity of the areas analyzed through the maps, and distinguishing them using the heterogeneity of the elements that define the Ups. The landscape units were identified and classified according to the morphological aspects, observing their role in the hierarchy of the system that consists of the Basin. These Ups were classified in 3º levels, being the first level composed by the relief forms that support different systems; the second level consists of the interpretation of the lithological extract of the forms observed in the first level UPs; the third level consists in the interpretation of the use and occupation of the land, in order to subsidize the reading of the landscape, and to understand the processes that lead to its degradation. Thus, the general objective of this dissertation is to identify, classify and analyze the landscape units (UPs) that make up the Jagui river basin, located in the Iguatemi - Mato Grosso do Sul - Brazil Planning and Management Unit. It is observed that the morphology of the BH Jagui, composed of homogeneous forms, due to regional geomorphology, conditions Landscape units that reflect this homogeneity. In summary, the scenario observed at BH Jagui points to soil loss, which tends to follow the suppression of vegetation, since both have complex and co- dependent functions. Given the current configuration of polítical processes in Brazil and South America, I believe that planning will have as its philosophy the neoliberal economy, one can glimpse the maximization of environmental impacts in the area of study, and the perpetuation of the social conditions presented. In this way, we suggest more in-depth studies that can clarify the relationship between politics and the environment, not only in BH Jagui, but also in the other sub-basins that make up the southern portion of Mato Grosso do Sul state.
