Hainan Bawangling National Nature Reserve, Changjiang 572722, Hainan, ChinaIn order to understand the regeneration ability of Dacrydium pierrei under nature condition, the seed rain, soil seed bank and seedlings and saplings of D. pierrei at Bawangling, Hainan, China were observed for 3 years, and the relationship between environmental factors and the number of seedlings and saplings was analyzed. The results showed that the effective seeds number of seed rain and seed bank of D. pierrei was very litter and had seasonal differences. There was an on-and-off-year phenomenon of fruiting in population. The dispersal density of seed rain gradually decreased with the increment of distance to mother tree. The seed number of soil seed bank in the litter layer accounted for the largest proportion, but the viable seed number was small. The suitable altitude range for seedlings and saplings was from 800 to 1 400 m, and the longitude, latitude, slope had significant correlation with the distribution of seedlings and saplings. Therefore, artificial managements, such as picking seeds in suitable season, improve the quality and quantity of seed sources, and removing litter under forest, enhance seed germination ability, should be considered appropriately for D. pierrei regeneration.
