Abstract Ulmus macrocarpa Hance can form monodominant
woodlands in the semiarid Keerqin sandy lands, China. Methods of
sampling at meter intervals from the bases of trees at the woodland
edges and isolated trees, respectively, were employed along vertical
sections in different directions. Using statistical methods based on
the density function of the Weibull distribution, the patterns of seed
dispersal and the spatial expansion response of U. macrocarpa, which
is a typical anemochorous plant, were analyzed. Although as an effect
of the wind direction varying owing to the monsoon, there were differences
in the degree of dispersal of seeds in terms of… More >
