By field sampling, some original soil microbiotic crusts were gathered and their physico-chemical properties were analyzed. The results revealed that the longer the sand dunes have been fixed, the thicker and the more biocrusts are formed. The thickness of the crusts under four different types of plant community ranges within 0.3 ~ 1.5cm.
