摘 要(英文)：The soils were chosen from monsoon evergreen broad-leaved, mixed coniferous and broad-leaf forest, Pinus massoniana forest in Dinghushan, and the reserves, component, diversity pattern and life form of the seed bank of forest soil were studied. First,the soil was chosen from two levels. Then it was air-dried. The seeds were sifted by select soil samples. Finally, the seeds were classified
and identified, and the component of the soil seed bank was inspected by the soil core experimentation. The result showed that,
in four sampling spots, the Shannon and Simpson index of the topper seed are obviously higher than the subsoil. Herbage is the principal
part of the three forests both at its variety and number. Especially in needle forest, the reserves of seed have distinct predominance.
The proportion of herbage seed in the bank are reduced, with the increasing of succession age. Otherwise, the predominant
components in the seed bank are different from the subaerial predominant vegetation at correspond layer. The result showed that the growth of subaerial parts of plant community isn’t obviously isochronous with the seed bank. So the inherent potential of soil seed bank has important influence on the regeneration of forest and the dynamic succession of plant community.
