| 摘 要： | 土壤动物个体数量和类群数随着际的推进而增加，8月份达到最高值。8月份和9月份，豚草发生地土壤动物个体数量和类群数明显少于对照样地。豚草对于土壤动物的抑制作用具有类群上的选择性，对线虫类和线蚓类的抑制作用更强。豚草对土壤动物的影响，生殖生长期大于营养生长期，普通豚草大于三裂叶豚草，豚草纯群落大于豚草与其它植物混生群落。 |

| Abstract: | The number of individuals and groups of soil animals increased with the proceeding of growth seasons and attained the maximum value in August.In August and September,the number of individuals and groups of soil animals in ragweed habitats was remarkably less than that in other habitats.Ragweeds showed selective containment on soil animal groups,and it was more significant for Nematoda and Enchytraeidae.The impacts of ragweed on soil animals in reproductive period exceeded that in vegetative period,that of A.artemisiifolia exceeded that of A.trifida, that in pure ragweed community exceeded that in the community with ragweed and other plants. |
| Keywords: | ragweed habitat soil animals community characteristic dynamic |
