The Relationship analysis of plant species of soil seed bank and the soil vegetation in the collecting field

There are many subjects to have to be studied before the soil seed bank is applied,which is used as one of the approaches in the regional vegetation restoration.And it is important to know the relation of germinant plant species of soil seed bank and the soil vegetation in the collecting field.Based on the ecological significance of soil seed bank,this research discusses the probability of the urban natural vegetation restoration by using the forest top soil in for the first time.With the material of top soil 5cm deep,20 m×20 m,which is under the woods of Chinese Cork Oak(Quercus variabilis)in the urban constructing lands of Osaka International Culture Park in Minoh city,Osaka prefecture,the research carried out a small-scale spreading test of forest top soil.A small piece of wasteland was used as the test field,which is in Yamadaike Park in Hirokata city,Osaka prefecture.There were 4 test areas,and each test area included 7 disposal areas.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.
