摘要：

Biological soil crust exists in desertification-prone areas.This paper focuses on ecological function of biological soil crust,including water relations,soil stabilization,carbon and nitrogen fixation,albedo and effects on vascular plants.Some preliminary suggestions are given for further understanding the relationship between biological soil crust and revegetation of degraded ecosystem in desertification-prone areas in Northwestern China.
