Effect of shrub density on grain sizes and threshold wind velocity
摘要
Abstract
Based on the collected sand samples around the shrubs with different densities at the Sand Drift Observation Station of Chinese Academy of Sciences, the grain size parameters and the threshold wind velocity are studied through laboratory analysis and wind-tunnel experiments. The results reveal that the modal shape of the particle size-frequency distribution belonged to high-narrow peak, and the existence of shrubs was advantageous to hold fine sand and medium fine sand. The density of shrubs had important influence on the grain size parameters and threshold wind velocity and the most effective densities were 12％ ～ 15％ for abating wind erosion.关键词
