生物土壤结皮（BSC）是外部光合自养生物和内部异养群落的整合。沙埋是一种普遍存在的干扰现象，影响生物多样性和生态功能，但沙埋对干旱沙漠微生物群落的影响却知之甚少。本文基于长期野外实验，利用高通量测序技术，评估了沙埋对腾格里沙漠三种沙埋深（0、0.5、10 mm）下两个典型演替阶段（演替早期蓝藻结皮和演替后期混合结皮）细菌和真菌群落的影响。我们发现细菌和真菌群落的多样性、丰度和组成都因沙埋处理而改变。在未埋藏和埋藏（浅层和深层）BSC 中鉴定出不同的指示类群。沙埋引起的土壤性质变化被认为是生物干细胞中细菌和真菌群落组成变化的可能原因。
Biological soil crusts (BSCs) are an integration of external photoautotrophs and internal heterotrophic communities. Sand burial is a ubiquitous disturbance that affects the biodiversity and ecological function of BSCs, but little is known about the influence of sand burial on microbial communities in arid sandy deserts. Here, based on a long-term field experiment and utilizing high-throughput sequencing, we assessed the influence of sand burial on bacterial and fungal communities inhabiting two typical successional stages of BSCs (cyanobacterial crusts for early successional stage and mixed crusts for late successional stage) at the three-sand buried depth (0, 0.5, and 10 mm) in the Tengger Desert, Northern China. We found that the diversity, abundance, and composition of the bacterial and fungal communities were all altered by the sand burial treatment. Different indicator taxa were identified in unburied and buried (shallow and deep) BSCs. Changes in soil properties caused by sand burial have been suggested as a possible cause of changes in the bacterial and fungal community composition in BSCs.
