英文摘要Purpose A general understanding of the influence of different plant species on soil quality improvement under drought stress is vital for planning the restoration of degraded land resources, especially in the context of global warming. Methods In this pot study, we planted Setaria viridis, Stipa bungeana, and Bothriochloa ischaemum, which are typical grass species on abandoned farmland, succeeded by grassland, in the Loess Plateau of China, under optimal soil water conditions and under water deficit (i.e., 80% and 60% of soil field capacity, respectively). Rhizosphere soil samples of the three grass species were collected after 76 days of growth, and 21 soil properties were determined as potential indicators of soil quality. Four rhizosphere soil quality indices (SQI) were computed using linear/nonlinear scoring functions and additive/weighted additive methods by the selected minimum dataset (MDS). Results L-leucine aminopeptidase, cellobiohydrolase, phenol oxidase, total phosphorus, available phosphorus, nitrate nitrogen, water-soluble nitrate nitrogen, and water-soluble ammonium nitrogen constituted the MDS for SQI calculation. The nonlinear weighted additive index best discriminated the effects of grass species under drought stress. Rhizosphere SQI did not significantly differ among the three grass species under optimal water conditions, but drought stress exerted a positive effect on rhizosphere SQI, which was significant for S. viridis. Conclusion Short-term drought stress increased rhizosphere SQI, especially at the preliminary succession stages. Furthermore, the relatively stable rhizosphere SQI of plant species at the later-successional stages suggests that the later-successional plant species resisted drought stress better; this aspect warrants further investigation.
