Geodiversidade e geopatrimônio no planalto de diamantina, Espinhaço Meridional (MG): sistemas geomorfológicos e estrutura da paisagem

Abstract

This current research dwell itself on the exploration of the theoretical and methodological improvements of the studies which envolve the thematics related to the geodiversity and geopatrimony from their interaction with the landscape structure, engendering a perspective capable of relating qualitative aspects in line with quantitative ones, traditionally given by the geodiversity index. For this purpose, the Diamantina Plateau, located in meridional Espinhaço (MG), was chosen because it brings together differentiated, unique, exceptional and exception landscape elements, endowed with functional, scientific-educational, intrinsic, cultural, esthetic and economic values. In order to achieve the proposed aims, it was elaborated a comparative between cartographic techniques, among them: A) A geodiversity map given by the geodiversity index (G.I) and represented by 1 km² squares; B) A geodiversity map given by the G.I by 1 km² squares and grouped according to a proposed landscape classification and its degree of complexity; C) A geodiversity map given by the G.I interpolated by the inverse weighting (IDW) and grouped by landscape classification classes and their degree of complexity;D) A geodiversity map given by the G.I ponderation and represented by 1 km² squares considering the landscape classification and its degree of complexity in the exposition and E) A geodiversity map result of the weighting of G.I and represented by IDW and by landscape classification e by its degree of complexity. Based on the interpretation of the obtained results it was defined the most adequated methodology for the sector, favoring to stablish a relationship given by the abiotic aspects of the landscape with its interior organization and to understand how these arrangements are distributed in the Diamantina Plateau. Therefore, it was presented a purpose relating the sectors that count with a very low geodiversity such as very simple structures áreas and consequently dominated, homogeneous landscapes, without the formation of mosaics and counting on uniform and non-diversified physical attributes; the sectors that presente a low geodiversity, such as simple structures, relatively homogeneous, with the presence of few mosaics; having restricted variations of attributes and characterized as bidominant; the sectors which present a medium geodiversity like transitional structure areas, represented by mosaic and heterogeneous landscape, with distinct variations in its atributes and being subdominants, containing well-marked units with accessory structures; sectors with high geodiversity like complex structures, resulting in rare, unique and heterogeneous landscapes, characterized by mosaic landscapes and the sectors presenting very high geodiversity related to very complex structures resulting in unique, heterogeneous and very divided.
