When the seed of Castanopsis fargesii entered the seed bank, there was no difference in the total number of seed between the mast year and the lean year. But the component of seed bank in mast year was different from that in lean year. The number of the germinative seed in mast year was 72. 15 - 74. 32m - 2, and that in lean year was only 3. 47m-2. In the aeed bank, the seed are lost largely because of the predation by animal and larvae and the rotting led to by mould The number of the Germinative seed in seed bank was small when the germination of the seed in soil begin. It was 15. 98 - 17. 14m - 2 in mast year. In lean year, there was no germinative seed in seed bank when germination occurs. In the seed bank, the ripe seed are mainly located in the litter, and the unripe seed could be located in the 5 - 10cm layer of soil below the surface of the soil.The refreshment of ChslanoPsis Fargesii was dominated by the mast year- The dormant stage of the seed of Chstanopsis fargesii are two or three months. The seed was germinativeless after one year. The seedling was maintained for 1 - 4 years in the forest in order to wait the occurrence of est gap. Axnong the process of refreshment, offspring was losed largely at three stages.
