文摘

Biocrusts can improve soil organic matter and accumulate fine soil particles. Soil erodibility decreased with development of biocrusts. Biocrusts reduced sediment yield by about 90% through alteration of soil properties. Sediment loss is determined by biocrust composition and successional stage. Moss crust was a strong predictor of soil erodibility on the Loess Plateau.
