摘要： 水位脉动、干湿交替是影响消落区植物群落分布和土壤稳定性的关键环境驱动力，消落区植物群落是影响土壤团聚体稳定的重要因素，研究消落区植物群落结构和功能性状对土壤团聚体稳定性的影响有助于预测消落区植物演替过程和揭示其对岸带稳定的影响机制。本文总结了国内外相关研究，综述了植物群落对干湿交替环境的响应，同时基于植物功能性状对干湿交替的响应重点阐述了其对土壤团聚体粒径稳定性的影响。未来研究应该重点关注根系构型性状和根际微生物性状对土壤团聚体的影响，并加强消落区不同胁迫强度和演替阶段植物群落组成、地上-地下性状对土壤团聚体稳定性的研究，进而探究水位脉动条件下植物群落对土壤团聚体稳定的影响机制，为消落区生态调节、生态恢复提供理论支撑。

Abstract: Water-level fluctuation and dry-wet alternation are the key factors affecting plant community and soil stabilization in the water-level fluctuating area (WLFA). Meanwhile, plant community greatly contributes to the soil aggregate stability in the WLFA. Studying the influence of plant community structure and plant functional traits on soil aggregate stability in the WLFA can help predict plant succession and reveal its influence mechanism on bank stability. We reviewed the responses of plant communities to water-level fluctuation, and focused on the impacts of plant functional traits on soil aggregates in the WLFA. In future studies, we should pay more attention to the traits of root architecture and rhizosphere microorganisms, and strengthen the studies of plant community composition, the effects of aboveground and belowground traits on the stability of soil aggregates. Such efforts will be helpful for understanding the influence mechanism of plant community on soil aggregate stability under hydrological stresses, providing theoretical support for ecological regulation and restoration in the WLFA.

Key words: dry-wet alternation, plant-soil, rhizosphere microbial trait, root architecture trait.
