The Morphoclimatic Domain of Cerrado is located in the Brazilian territory, and it is a central area of great importance for the ecological scenario of Brazil. This area has undergone strong anthropic pressure in the last 60 years, especially due to the expansion of agribusiness—a warning sign for the conservation of its natural resources. Studies on geodiversity and biodiversity have sought to contribute with data for maintaining the landscapes of this region. The objective of this proposal is the generation of a geobiodiversity index capable of indicating the most relevant areas of geological, geomorphological, and vegetation aspects to be preserved and conserved within existing legal instruments. The methodological procedures were centered on segmenting the area in 2.472 hexagonal cells, which were subjected to a spatial matrix analysis in GIS and geostatistical environments capable of articulating the various elements and generating an agglutinating index for each cell. The result indicates 276 areas with the highest index value, presenting, therefore, possible classified areas. This index is an attempt to draw attention to Cerrado and the importance of its conservation.

应用于巴西塞拉多地形气候域的地球生物多样性指数的提案

塞拉多地貌气候域位于巴西境内,是巴西生态场景中具有重要意义的中心区域。在过去的 60 年中,该地区经历了强大的人类压力,特别是由于农业综合企业的扩张——这是保护其自然资源的警告信号。对地质多样性和生物多样性的研究试图为维护该地区的景观提供数据。该提案的目标是生成一个地球生物多样性指数,该指数能够表明在现有法律文书中需要保护和保护的地质、地貌和植被方面的最相关区域。方法程序集中在分割 2.472 个六边形单元中的区域,在 GIS 和地统计环境中进行空间矩阵分析,能够阐明各种元素并为每个细胞生成凝集指数。结果显示了 276 个具有最高指数值的区域,因此,呈现了可能的分类区域。该指数试图引起人们对塞拉多及其保护重要性的关注。
