为探讨退化喀斯特森林生态系统恢复和重建机理 ,了解土壤种子库在植被恢复中的作用 ,采用人工模拟自然的方法 ,种子埋藏试验表明种子库中种子命运受种子休眠特性、动物活动、种子埋藏条件的影响。休眠、发芽、霉烂、被害和损失等不同命运及其比例决定了种子库种子的输出格局
In order to understand the mechanism of the restoration and reconstruction of degraded Karst forest ecosystem and to understand the role of soil seed bank in vegetation restoration, artificial simulation of natural methods was used. Seed burying experiments showed that the seed fate of seed bank was affected by seed dormancy, animal activities, seed burying conditions Impact. The different fate of dormancy, germination, mildew, victimization and loss and their proportions determine the output pattern of seed bank seeds
