| Abstract: | Biological soil crusts play an important role in most arid and semi-arid desert ecosystems.This paper is based primarily literature reviews and research papers in current reported,introducing the present study and development on the biological soil crusts in abroad.Increasing the understanding of biological soil crusts ecological functions,including soil stability and erosion,atmospheric nitrogen-fixation,nutrient contributions to plants,soil-plant-water relations,infiltration,seedling germination,and plant growth.In order to protect crumbly biological soil crusts that composed of microphysics in deserts. |
