Abstract

Elucidating the climate feedback due to forest cover loss is critical for a comprehensive understanding of the role of forests in mitigating climate change. Current research studies predominantly focus on the impacts of permanent forest conversion, often overlooking the effects of recurrent disturbances such as fire and harvest. This study addresses this gap by examining the impact of forest cover loss caused by two distinct drivers in China over the period 2003–2020. Our analysis revealed that fire-induced forest cover loss accounted for approximately 10% of total forest cover loss in China. The immediate (i.e., 1 year after disturbance) changes in land surface temperature (ΔLST) due to fire were higher (ΔLST = 0.11°C, interquartile range (IQR): [−0.02°C–0.23°C]) compared to those caused by harvest (ΔLST = 0.04°C, IQR: [−0.01°C–0.09°C]). This finding highlights the immediate warming effect of fire-induced forest cover loss, was about triple as large as that caused by harvest. Our analysis also found that the warming effect post-fire gradually lessened but still maintained approximately 0.02°C 5 years later. Change in evapotranspiration is a primary factor influencing surface temperature changes following forest disturbances. Our study provides comprehensive insights into the differential and persistent effects of LST responses to fire and harvest, underscoring the importance of understanding the climate feedback from forest dynamics from different drivers.

中国森林覆盖丧失对地表温度的影响因驱动因素而异
要全面了解森林在减缓气候变化方面的作用,阐明森林植被丧失造成的气候反馈至关重要。目前的研究主要集中在永久性森林转换的影响上,往往忽略了火灾和采伐等经常性干扰的影响。本研究通过考察 2003-2020 年间两种不同的驱动因素在中国造成的森林植被损失的影响,填补了这一空白。我们的分析表明,火灾导致的森林植被损失约占中国森林植被总损失的 10%。与采伐造成的地表温度变化(ΔLST = 0.04°C,IQR:[-0.01°C-0.09°C])相比,火灾造成的地表温度直接变化(即干扰后 1 年)更高(ΔLST = 0.11°C,四分位数间距(IQR):[-0.02°C-0.23°C])。这一发现凸显了火灾引起的森林植被损失所产生的直接变暖效应,是采伐造成的变暖效应的三倍。我们的分析还发现,火灾后的升温效应逐渐减弱,但 5 年后仍维持在 0.02°C 左右。蒸散量的变化是影响森林扰动后地表温度变化的主要因素。我们的研究全面揭示了地表温度对火灾和采伐的不同和持续影响,强调了了解不同驱动因素的森林动态对气候反馈的重要性。

期刊介绍: JGR-Biogeosciences focuses on biogeosciences of the Earth system in the past, present, and future and the extension of this research to planetary studies. The emerging field of biogeosciences spans the intellectual interface between biology and the geosciences and attempts to understand the functions of the Earth system across multiple spatial and temporal scales. Studies in biogeosciences may use multiple lines of evidence drawn from diverse fields to gain a holistic understanding of terrestrial, freshwater, and marine ecosystems and extreme environments. Specific topics within the scope of the section include process-based theoretical, experimental, and field studies of biogeochemistry, biogeophysics, atmosphere-, land-, and ocean-ecosystem interactions, biomineralization, life in extreme environments, astrobiology, microbial processes, geomicrobiology, and evolutionary geobiology
