| 摘要: |
| 为了了解围栏这一人为手段对山区草地植被下土壤动物的影响,在草原围栏措施下,对新疆巴音布鲁克草原植被、地下根系、土壤理化性质进行了实地监测,比较了草原围栏内外土壤动物的类群组成、个体数量及生态分布。结果表明,围栏内土壤动物多样性指标高于围栏外,如类群数围栏内为19种,围栏外为8种;个体数围栏内为234个,围栏外为125个;Shannon-Wiener指数围栏内为0.653,围栏外为0.498;即围栏有利于草原植被下土壤动物多样性的保持和提高。 |

| Abstract: |
| In order to investigate how the fencing, an artificial means, affects the distributions of soil animals beneath mountainous lawn vegetation,the plants,the roots and the soil physicochemical properties are monitored and the group composition, individual amount and ecological distributions of soil microorgan- ism inside fences and outside fences in Bayinbuluke of Xinjiang are compared. The results show that the diversity of the soil animals inside fences is higher than that of outside fences. The group amount inside is 19 and the one outside is 8. The individual amount inside is 234 and the one outside is 125. The Shannon-Wiener index of soil animals inside is 0. 653 and the one outside is 0. 498. So the fences are useful to preserve the better soil animals diversity beneath mountainous lawn vegetation in Bayinbuluke. |
