摘　　要： 多年来,围垦、砍伐等长期过度的人类活动和自然因素的综合作用,严重影响和破坏了土壤种子库完整性和河漫滩植被的生物多样性。在此根据国内外最新研究进展,分析了种子库在地表植被演替动态中的作用、演替实质以及河漫滩种子库的保护生物学意义,并提出了深入开展河漫滩土壤种子库研究的意义。 Under long-time reclamation and deforestation and natural disasters, the completeness of soil seed bank and the biological diversity of riparian vegetation have been seriously destroyed. According to the latesl research advances both at home and abroad, the functions of seed bank in the evolution of surface vegetation were analyzed, the biological significance of preserving the riparian seed bank was studied, and finally the significance of carrying out the studies on riparian seed bank was pointed out.
