Based on the investigation of a transect (20m wide and 80 m long) along a gradient (bottom, middle, and top) of a dune, whose height was about 5apprx10m, the population dynamics in young Pinus sylvestis var. mongolica stands was studied. The results showed that both skewness and height inequality declined before the self-thinning process occurred. Age, initial growth status, density of the population, and neighborhood competition were the main factors affected height inequality. The location at sand dune was also an important factor, and its effect was more obvious than that of density.
