摘要：

为了研究石漠化治理区土壤动物的动态变化。对毕节鸭池、清镇红枫湖和贞丰-关岭花江石漠化区的土壤动物的空间格局进行了调查，并对土壤动物在石漠化生态环境恢复中的功能研究作了总结。结果发现：喀斯特石漠化治理区以杂食性和植食性功能类群为主，捕食性和腐蚀性功能类群分布较小。随着纬度的增加，Shannon-wiener多样性指数和Margulef指数有增加趋势，而Pielou指数和Simpon指数不存在这种趋势；随着石漠化程度的加深，物种数和个体数有减少趋势；随着土层的加深，各研究区的土壤动物的物种和个体数有减少趋势，土壤动物表聚现象显著。受气候干旱的严重影响，土壤动物的年度变化波动较大。蜱螨目和弾尾目的抗干扰性、抗旱性较强，在凋落物的分解中充当重要的角色，因此，可把这两类物种作为改良土壤的主要动物。

Abstract:

In order to study the dynamic change of soil animal in desertification control rock。The writer has surveyed the rocky desertification area’s soil fauna’s distribution of Yachi of Bijie, Hongfeng Lake of Qingzhen and Huanjiang Area of Zhenfeng-Guanling, and function study of soil animals on the ecological environment restoration in rocky desertification were summarized. The results found that the main functional groups of soil fauna were omnivorous and phytogyagous in the three rocky desertification areas. And predatory and corrosive functional groups were limited. As the latitude increase, the Shannon-wiener diversity index and Margulef index increase as well. But the Pielou and Simpon indexes did not have this response; the numbers of species and individual decrease as the deepen of rocky desertification degree or soil depth. Soil fanua’s surface aggregation phenomenon was obvious; Been effected by severe drought, the quantity of soil fanua changed a lot annually; With strong anti-jamming ability and drought resistance, Acarina and Collembola play an important role in litter’s composition. So these two species could be used for soil improvement.
