Abstract

The Brazilian Cerrado, renowned as the most biodiverse savanna, is characterized by its pronounced climatic seasonality, diverse vegetation mosaic, and distinct topographic variations. Natural protected areas (NPA) within this biome play a pivotal role in safeguarding both biodiversity and natural resources. The objective of this study is to analyze the dynamic shifts in land use and land cover across seven NPA and their corresponding buffer zones (BZs) within a Cerrado region situated in Central-West Brazil. This research encompasses a comprehensive multitemporal analysis of satellite imagery spanning the period from 1985 to 2018 utilizing a geographic information system (GIS). The variability in land use and land cover classes is considerably more constrained within the NPA than BZs. The Templo dos Pilares Municipal Natural Park exhibits substantial expanses of preserved vegetation, while the Nascentes do Rio Taquari State Park demonstrates an extensive prevalence of pasturelands. The NPA exhibit coherent patterns of land cover transformation within their respective BZs. However, alterations in the landscape within the BZs offer insights into potential forthcoming challenges to the NPA. Escalated land use within the surrounding matrix of protected areas presents a formidable obstacle to biodiversity conservation, owing to extraneous pressures. A comprehensive understanding of the spatiotemporal distribution of land use and land cover within safeguarded Cerrado regions contributes substantively to the augmentation of management, preservation, and conservation endeavors over time.

摘要

巴西塞拉多被誉为生物多样性最丰富的稀树草原，其特点是气候季节性明显、植被镶嵌多样且地形变化显著。该生物群落中的自然保护区在保护生物多样性和自然资源方面发挥着关键作用。本研究的目的是分析巴西中西部一个塞拉多地区内七个自然保护区及其相应缓冲区土地利用和土地覆盖的动态变化。本研究利用地理信息系统（GIS）对1985年至2018年期间的卫星图像进行了全面的多时相分析。与缓冲区相比，自然保护区内土地利用和土地覆盖类别的变异性受到更大限制。皮拉雷斯市政自然公园有大片保存完好的植被，而塔夸里河源头州立公园则有大面积的牧场。自然保护区在其各自的缓冲区内呈现出连贯的土地覆盖变化模式。然而，缓冲区内地貌的变化为自然保护区未来可能面临的挑战提供了线索。由于外部压力，保护区周边区域土地利用的增加对生物多样性保护构成了巨大障碍。全面了解受保护的塞拉多地区土地利用和土地覆盖的时空分布，将随着时间的推移对加强管理、保护和养护工作做出重大贡献。
