Résumé partiel
Biological Soil Crusts（BSCs）widely arise in places whose weather is arid and semi-arid around the world.As a significant element to improve the desert ecosystem,the BSCs have multiple functions,such as reinforcing the environmental stability,and expediting the process of environmental recovery and rebuilding.Soil aggregation is a vital part of the process in which the soil plays its role,and is a crucial indicator to show the quality of the soil.The mode of form soil aggregation is usually utilizing the physical and chemical path,and the process of the soil aggregation form relates to BSCs’development.Aerobic anoxygenic phototrophic bacteria（AAPB）play a crucial role in BSCs’formation and development and maybe play a vital role in soil aggregation formation and stabilization.There is rarely reported on the community structure and diversity of the AAPB in different soil aggregations.In this research,BSCs collected from the eastern part of the Kubuqi desert.Using the high-throughput sequencing platform-Miseq to contrast the cyanobacterial crusts and moss crusts’the diversity and community structure of AAPB at different soil aggregation combined with the correlation analysis of soil chemistry and soil enzyme activity.T
