土壤种子库在荒废地植被恢复工程中的应用

以日本大阪府箕面市大阪国际文化公园都市建设地的栓皮栎（Quercus variabilis）林下5cm厚表土为材料，以大阪府枚方市山田池公园的一隅荒地为试验地，做小规模的森林表土铺撒试验。从土壤种子库的生态学意义出发，探讨森林表土作为植被恢复绿化手段的可能性。对土壤种子库的植物种类组成、不同处理区出芽个体数状况、幼苗早期的生长情况、植被的形成、出芽植物种类与土壤采集地植被的关系以及不同的处理对出芽植物的影响等方面做了分析研究。

Application of soil seed bank in wasteland revegetation project

With the material 5cm deep of top soil,which is under the woods of Chinese Cork Oak(Quercus variabilisi)n the urban constructing lands of Osaka International Culture Park in Minoh city,Osaka prefecture,the author carried out a small-scale spreading test of forest top soil.A small piece of wasteland is used as the test field,in Yamadaike Park in Hirokata city,Osaka prefecture.Based on the ecological significance of soil seed bank,the purpose of this research is to discuss the possibility of revegetation using forest top soil.Furthermore,the research analyzes the vegetation species of soil seed bank,the number of germinant plants in different treatments,the status of seedling growth in the early time,the forming of vegetation,the relationship of the germinant plant species and the vegetation in the soil collection area and the effect of different treatments on the germinant plants and so on.
