Abstract

Pinus sylvestris var. mongolica （Mongol scotch pine），which is important for degraded ecosystem reconstruction and for establishment of green ecological barriers in northern China，adapts well to cold，droughty，and barren environments with favorable regeneration capability when wind erosion is controlled and shifting sand is fixed. This research was conducted to explore the regeneration potential of Mongol scotch pine and to promote its natural regeneration process in sandy lands. Based on the traditional community investigation and data statistical analysis，the conclusion can be drawn that the Mongol scotch pine in Hulun Buir sandy land distributed with great regeneration potential. Results showed that seedling density on the north-facing slope was four times larger than density on south-facing slope，and the Mongol scotch pine forest showed the trend of northward expansion from large-scale view. The forest seedling population age structure showed a greater percentage of young growth. Also，the seedling population age pyramid was a stable balanced type. Additionally，the seedling population had a clumped distribution pattern with high contagion and diffusion resulting in high spatial dispersion to population seedling density.［Ch，1 fig. 4 tab. 19 ref.］
