Abstract: The characteristics of soil fauna community structure of tea plantation and artificial plantation were studied. Soil macrofauna were picked up by hand in the fields. Mesofauna and microfauna were separated and collected from the soil samples by Baermann and Tullgren methods. The results showed that the soil fauna community structure is different between tea plantation and artificial plantation. The frequency and individuals of groups are dissimilitude. The Jaccard coefficients between the tea plantation and artificial plantation are 0.633, implying that soil fauna community structure of tea plantation and artificial plantation are different. However, the number of groups in the tea plantation is less than that in artificial plantation, but the proportions of dominant groups are much higher than those of the artificial plantation, the community is more single than that of the artificial plantation. The diversity index, individual richness index, individual evenness index and density community index of soil fauna community in the tea plantation are less than those in artificial plantation. Most of the groups, individual numbers, the diversity indexs are concentrated in the topsoil, and decreased with the increasing of soil depth under the litter layer both in the tea plantation and the artificial plantation. The ratio of Acarina and Collembola(A/C) in the tea plantation is higher than that in the artificial plantation, which is different from the other researches. The phenomenon is positively correlated with the litter quantity or a large number of Acarina in tea plantation.
