- Abstract:
-
The natural regeneration process of Mongol Scotch Pine in the sandy land is important to vegetation rehabilitation, degraded ecosystems reconstruction, sustainable sandy ecosystem benefit development, as well as the establishment of green ecological barriers in north of China. Results show that in Hunlun Buir Sandyland it is common to find the 10~20 years old Mongol Scotch Pine seedling association. Under the environment without all kinds of disturbance, there are lots of seedlings distribute around the mature individual plant, and 6~10 years old seedlings take an advantage percentage, 1~5 years old seedlings take the secondary percentage, which related to the recently drought climate and local overgrazing. With the individual plant growth from young to aging, the seedling density under the individual plant gradually increased, and seedling density is highest under the mature individual growth. After the calculating the seedling distribution type index, results show that Mongol Scotch Pine seedlings is clusted distribution pattern. Without the considering of the individual plant age class and its habitat spatial heterogeneity, the seedlings distribute assembly in a fan-shape region located in north to east direction below the mature growth crown.
