Abstract： Biological Soil Crusts （BSCs）and herbs are important components of desert ecosystems，they aredistributed in mosaic patern，the two are closely interconnected and interact with each other.Therefore， clarity of the influence of BSCs on herbaceous plants holds great significance for desert systemrestoration and biodiversityconservation.Basedonthis，the effects of three types of BSCs （algal crusts，lichen crusts，and moss crusts）and mixed crusts on herb seed banks，seed germination，growth，composition and diversity of herbs in the past 2O years were sorted out and summarized in this paper，meanwhile，the mechanism ofthe effects of BSCs on herbaceous plants was comprehensively analyzed，and future research directions on the effects of BSCs on herbaceous plants were proposed.

Keywords：artificial biological soil crusts;herb; desertification control; ecosystem function

生物土壤结皮（BiologicalSoil Crusts，BSCs）是由藻类、地衣、藓类等隐花植物和异养细菌、真菌等土壤微生物通过菌丝体、假根、分泌物等与土壤表层颗粒胶结形成的地表稳定复合体[1]。（剩余20731字）
