土壤动物类群与不同施肥制度之间的关系一直受到人们的关注。很少有人关注土壤动物对土壤肥力变化的反应。因此，本研究的目的是调查土壤动物群落对肥料管理措施的反应，探索土壤动物群落与施肥制度之间的相互关系，以确定对土壤肥力变化敏感的土壤动物物种或类群。长期定位施肥试验为不施肥对照，设置CK(对照)、N(合成氮肥)、NPK(氮磷钾)、OM(猪粪)、OMNPK(猪粪+氮磷钾)、RSD(秸秆还田)和RSDNPK(作物秸秆还田)6个施肥处理。有机肥(如猪粪或秸秆)的使用促进了土壤动物群落的多样性，因为有机肥为群落的生存和发展提供了丰富的有机质。此外，有机-无机复合肥(即OMNPK或RSDNPK处理)由于有机质丰富，养分供应充足，有利于土壤动物群落的丰富性和多样性。土壤动物群落指数(即TI值、DG(密度组)指数、线虫纲、轮虫纲、弹尾目和ORiatida)随土壤有机质的增加而呈现相同的趋势。因此，土壤动物群落指数可以用来反映土壤有机质含量等土壤肥力特征，但不能反映土壤肥力的综合评价。
The relationship between soil fauna groups and different fertilization regimes has been of continuous concern. Little attention has been paid to the response of soil fauna to changes in soil fertility. Thus, the aim of this study was to investigate the response of soil fauna communities to fertilizer management practices, to explore the inter-relationships between soil fauna communities and fertilization regimes so as to identify soil fauna species or groups that are sensitive to changes in soil fertility. This long-term fertilization experiment was conducted with a no fertilizer control and six fertilization regimes: CK (control, no fertilizer), N (synthetic N fertilizer), NPK (synthetic fertilizer: nitrogen, phosphorus and potassium), OM (pig manure), OMNPK (pig manure plus nitrogen, phosphorus and potassium), RSD (crop residues returned) and RSDNPK (crop residues returned with nitrogen, phosphorus and potassium). The application of organic fertilizers (i.e., pig manure or crop residues) promoted the diversity of the soil fauna communities due to the abundant organic matter the fertilizers supplied for the communities’ survival and development. Furthermore, organic–inorganic compound fertilizers (i.e., treatment of OMNPK or RSDNPK) were beneficial for richness and diversity of soil fauna communities due to their abundance of organic matter and supply of nutrients. Indices of soil fauna communities (i.e., TI, the DG (density-group) index, the number of individuals of Nemata, Lumbricida, Collembola and Oribatida) showed the same trend with an increase in the soil organic matter. Therefore, indices of soil fauna communities can be applied to indicate certain features of soil fertility, such as soil organic matter content, but they cannot be used to reflect integrated assessment for soil fertility.
