Abstract:
As an important biological factor in soil, soil fauna play an important role in soil nutrient cycling and energy flow, and an irreplaceable role in improving the ecology and environment of farmland ecosystem for restoring the degraded ecological function. We researched the soil fauna in maize fields of Basalt Platform, Granite Low-mountain, and Granite Hill on the Changbai Mountains in spring, summer and autumn of 2015. Soil macrofanual were collected by hand, and modified Tullgren funnel extractors were used for collecting the soil mesofauna. We obtained 2 956 soil fauna, belonging to 3 phyla, 7 classes, 16 orders, 42 groups. Oribatida and Isotomidae were dominant groups in different landforms. In farmland ecosystem of Changbai Mountains, the individual density and group number of soil fauna in Granite Low-mountain was the lowest; the individual density of soil fauna in basalt platform reached the highest in summer, whereas the Granite low-mountain and Granite Hill were the highest in autumn. The individual density of soil fauna had a surface accumulation, but it was not obvious in Granite Hill. The diversity of soil fauna was the highest in the Granite Hill, and the lowest in the Granite Low-mountain. In spring and summer, soil fauna diversity in the Granite Hill was the highest, and that in the autumn showed no significant difference.
