中文摘要	黄土高原是典型的生态脆弱敏感区和世界上水土流失最为严重的地区,也是当今我国生态恢复和生态文明建设的重点区域。生物土壤结皮是细菌、藻类、真菌和孢子植物与土壤颗粒胶结而成的有机复合体,是干旱半干旱地区地表系统的重要组成部分,它们对黄土高原的水土保护、养分积累和生态恢复具有重要的生态功能。本文论述了生物土壤结皮类型与演替过程;系统总结了黄土高原不同环境中生物结皮微生物和藓类的物种多样性、生态功能、人工生物结皮培养与生态恢复的研究进展与存在问题,最后从黄土高原生物结皮微生物多样性和功能群、生物结皮不同生物类群之间及其与种子植物的种间关系、生物结皮人工培养和生态恢复方面提出了研究建议与展望,以期对黄土高原生物结皮的相关研究提供参考。
英文摘要	Loess Plateau is one of the most serious areas of soil erosion in the world and a typically sensitive and ecologically fragile area. It is also key areas of ecological restoration and ecological civilization in China. Biological soil crusts (BSCs) are complex organic integrities of cyanobacteria, bacteria, eukaryotic algae, fungi, lichen and moss, gluing loose soil particles together, and are critical component of the surface system in arid and semi-arid areas, which plays important roles in soil and water conservation, nutrients accumulation and ecological restoration of the Loess Plateau. In this paper, BSCs types and their successional process were reviewed. We summarize microbial and moss diversity in BSCs, and their environmental influencing factors, ecological function, artificial BSCs and ecological restoration in Loess Plateau. The existing problems in previous research were also discussed. In further research, the authors suggest microbial diversity can change from descriptive work to mechanical exploration. More attention should be paid to microbial functional groups in BSCs and their driving effects on the biogeochemical cycle of key elements of C, N and P. Inter-specific relationship among microorganism, spore plant and seed plant should be included in BSCs in Loess Plateau. Future research should focus on the mechanism how cyanobacteria, eukaryotic algae and mosses in BSCs response to key environmental factors such as culture substrate, water, temperature, nutrients and pH. The technical system of artificial BSCs cultivation should be established in laboratory and field, which will lay a theoretical foundation for ecological restoration. This review will be beneficial to BSC research in Loess Plateau in China.
