摘要
生物土壤结皮广泛分布于干旱、半干旱的荒漠地区,是干旱、半干旱荒漠地区最具特色的景观之一。生物土壤结皮是荒漠地区碳氮的主要来源。本文主要综述了气候因素、结皮类型、干扰对生物土壤结皮碳氮循环的影响,对进一步研究生物土壤结皮有重要的意义。
Biological soil crusts widely distribute in the arid and semi -arid desert region and are one of the most unique desert landscapes of the region. Biological soil crusts are the main source of carbon and nitrogen in the desert region. In this paper, climate factors, the type of crusts, and disturbances on biological soil crusts carbon and nitrogen cycles are reviewed, which have important meanings for the further study of the biological soil crusts.
