文摘

Effects of revegetation on fine-root distribution are studied in a desert area. Fine roots distribute shallower along the 46-year revegetation chronosequence. Herbaceous cover and shrubs biomass affect fine-root length and mass, respectively. Soil particle size and its associated soil properties affect fine-root distribution. Fine-root length and mass negatively respond to soil water content in deep layer.
