%X In order to understand the effects of terrace hedgerows on the soil macrofauna diversity, soil macrofauna was investigated during winter 2006 and spring 2007 in five land\|use systems i.e. mulberry orchard, mulberry field margin, citrus orchard, cirtrus field margin and farmland. A total of 4533 soil macrofauna individuals were captured and classified into 3 phylums, 9 classes. The results showed that individual density, group number and DG diversity index of soil macrofauna community varied significantly with land use systems. The three indicators were significantly higher in the mulberry field margin and citrus field margin than in the farmland both in winter and spring, and higher in the mulberry orchard and citrus orchard than in the farmland in winter. The individual density and group number decreased with the increase of soil depth in five land\|use systems, same trend has been found for the vertical distribution of soil water content, total N and organic matters. Principal component analysis showed that the soil macrofauna communities of mulberry field margin, citrus field margin and citrus orchard were significantly different from mulberry orchard and farmland, and the soil macrofauna community of mulberry orchard was also significantly different from farmland. The study suggests that terrace hedgerows play an important role in conserving soil macrofauna diversity.
