4The low similarities betweenseed banks and the established vegetation were considered to be the consequences ofthe frequent presence in the established vegetation but not in seed banks of someperennial rhizomatous plants which mainly depended on vegetative propagation toregenerate;insignificant difference in the species composition of seed barks amongtransects, might be accounted for by the fact that the flood drift had functioned as adisseminator for propagules;and with the intensifying of the flooding disturbance,both species diversity and the similarity between seed banks and establishedvegetations declined.

4种子库与地上植被相似性普遍较低，其原因是主要靠营养繁殖以更新种群的多年生根茎植物经常在植被中出现而不在种子库中出现；受水淹干扰的样带之间种子库的种类组成差异不大，说明洪水漂移行使了繁殖体传播和散布的功能；随水淹干扰强度增加，种子库物种多样性指数减小，种子库与地上植被的物种组成相似性下降。
