| 摘 要： | 对1个物候期内紫茎泽兰土壤种子库的活体进行调查，掌握土壤中紫茎泽兰种子活体的动态。结果表明，在紫茎泽兰分布区内的退耕地、桐林地、荒山和马尾松幼林地等均具有紫茎泽兰种子长久性土壤种子库特征；在土壤中的垂直分布方面，种子活体数土壤表层（0～2cm）〉2～5cm土层；紫茎泽兰土壤种子库的种子贮藏量与人为干扰有关，人为干扰较大的退耕地、马尾松幼林地〉荒山〉桐林地。 |

| Abstract: | Living body of soil seed bank of Eupatorium adenophorum in a phenological period was investigated to master the dynamic changes.The results showed that E.adenophorum has a persistent soil seed bank feature in many of its distribution areas including returned farmland,Tung tree forest land,waste hill,young Masson pine forest land,etc.The living seed number in soil layer of 0-2 cm was higher than that in soil layer of 2-5 cm.Seed amount in soil seed bank was related to the human disturbance.The seed amount of... |
