So there were 28 test fields in total. The research results showthat the plant species of soil seed bank has a low relationship with the vegetation in the collecting area, while which has close relationship with the seed disseminative type. The results also show that the tree species, number of germinant plants and the number of surviving plants are very different with the different covering thickness of top soil.

研究结果表明：土壤种子库植物种类组成与表土采集地的植被关联性较低，但与种子散布型关系密切；表土的不同铺撒厚度在木本植物出现的种类、出芽个体数、生存个体数等方面都表现出明显的差异性。

It was shown that there were 23 plants showing stronger inhibitory effect on Ligularia sagitata seed germination and reducing the seed germination index (M0.50), and there were nine plants that could significantly inhibited Ligularia sagitata but show less injurious effect and even promoting effect on the herbage.

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。
