By the method of hand-sorting, and using the indices individual number, group number, and biodiversity, the changes in the soil macrofaunal community under the grassland restoration from cropland in Wuchuan County, Inner Mongolia were investigated. A total of 1479 soil macrofauna belonging to 3 classes, 7 orders and 41 families were captured. After the grassland restoration from cropland, the group number, individual number, and biomass of soil macrofauna all had an increasing trend, and the biodiversity of soil macrofaunal community reflected by DMa and DG increased significantly. However, due to the short term of cropland rehabilitation, the Shannon-Wiener index H' and the Pielou evenness index E of the soil microfaunal community in grassland were not higher than those in cropland. Different soil macrofaunal groups had different responses to the grassland restoration from cropland. The preferable approaches for the grassland restoration from cropland were planting Medicago sativa or planting Medicago sativa + Artemisia sp.

    Numerous studies have suggested that biodiversity reduces variability in ecosystem productivity through compensatory effects1–6;that is, a species increases in its abundance in response to the reduction of another in a fluctuating environment1,7. But this view has been challenged on...
