Tropical dry forests (TDFs) are essential for environmental dynamics, especially in terms of climate variations. However, several anthropic factors have threatened the integrity of TDFs, and consequently the surface temperature (ST), which is a proxy variable for several environmental processes in TDFs. So, understanding their behavior is crucial. The objective was to analyze the behavior of surface temperature owing to conversion of TDFs into anthropic uses in northern Minas Gerais between 2007 and 2016. In 9 years, dry forests decreased by 22.9%, with pastures as the central driver (counted 93% of change). Between 2007 and 2016, there was an increase in ST by 1.55 K ± 1.15 K. When TDFs were converted to pastureland, the increase in ST was 2.21 K ± 1.39 K and for crops by 0.57 K ± 1.24 K. The remaining TDFs (2016) had an increase in their thermal average of 1.41 K ± 1.02 K. This analysis is essential for the adoption of conservation actions for the maintenance of ecological corridors in TDFs, considering their importance in the ecosystem context.
热带干旱林(TDFs)对环境动态至关重要,特别是在气候变化方面。然而,几种人为因素已经威胁到 TDF 的完整性,从而影响了地表温度(ST),ST 是 TDF 中几个环境过程的替代变量。因此,了解其行为是至关重要的。本研究的目的是分析 2007 年至 2016 年米纳斯吉拉斯州北部 TDF 转变为人为用途对地表温度的影响。在 9 年内,干旱森林减少了 22.9%,而牧场是主要驱动力(占变化的 93%)。2007 年至 2016 年间,ST 增加了 1.55 K ± 1.15 K。当 TDF 转变为牧场时,ST 增加了 2.21 K ± 1.39 K,而转变为农田时则增加了 0.57 K ± 1.24 K。2016 年剩余的 TDF 平均温度增加了 1.41 K ± 1.02 K。这项分析对于采取保护行动维护 TDF 生态走廊至关重要,因为它们在生态系统中具有重要意义。
