This study shows that by stabilizing the soil, biological soil crusts reduce global atmospheric dust emissions by 60%, corresponding to ~700 Tg of dust per year. According to models of biocrust cover loss, this effect will be reduced in the future, leading to increases in not only dust emissions but also global radiative cooling.

生物土壤结皮在当前和未来的全球沙尘循环中发挥关键作用

这项研究表明，通过稳定土壤，生物土壤结皮可将全球大气尘埃排放量减少 60%，相当于每年约 700 Tg 的尘埃。根据生物结皮覆盖损失模型，这种影响在未来会减弱，不仅会导致粉尘排放增加，还会导致全球辐射冷却增加。
