Comparisons of species composition in the forest survey and in the soil seed bank using two collection strategies: large number of small samples (LNSS) and small number of large samples (SNLS) to replace soils of secondary forest, shrub and grass land.

*Different uppercase letters indicate the significant difference between two SNLS sites.
** = 2c/(a+b), where c is the number of common species, a is the number of species in the vegetation and b is the number of species in the soil seed bank.

*不同大写字母表明两个SNLS样地（SNLS sites）之间存在显著差异。
**=2c/(a+b)，其中c为共有物种数，a为植被中的物种数，b为土壤种子库中的物种数。
