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 are widely distributed in arid and semi-arid desert areas and are one of the most characteristic landscapes in arid and semi-arid desert regions. Biological soil crusts are the main source of carbon and nitrogen in the desert. In this paper, the effects of climatic factors, crust types and disturbance on carbon and nitrogen cycling in biological soil crusts are reviewed, which is of great significance for the further study of biological soil crusts.
