Constructed wetlands (CWLs) are widely used for water environment protection. In some cases, CWL animals can help improve CWL treatment efficiency and contribute to CWL maintenance and management. However, while plants, microorganisms, and substrates in CWLs have received much attention, animals have been largely ignored. Therefore, the aims of this review are to determine the roles wetland animals play in the water environmental protection of CWLs. This study introduced species of wetland animals and the main factors that can affect their survival. The way in which CWL animals affect pollutants was discussed in detail from four perspectives: adsorption and bioaccumulation, bioturbation, and the influence of CWL animals on plants and microorganisms. The characteristics of CWL animals that can be used for biological monitoring are summarized, and the use of CWLs for the protection of wetland biodiversity is also discussed. Finally, some prospects are proposed for future research. This study will help researchers better understand the role of CWL animals in CWLs and encourage researchers to focus on studies of wetland animals.
人工湿地（CWs）被广泛应用于水环境保护。在某些情况下，CWs 动物可以帮助提高 CWs 的处理效率，并有助于 CWs 的维护和管理。然而，尽管 CWs 中的植物、微生物和基质受到了广泛关注，但动物却在很大程度上被忽视了。因此，本综述的目的是确定湿地动物在 CWs 水环境保护中的作用。本研究介绍了湿地动物的种类以及影响其生存的主要因素。从吸附和生物积累、生物搅动以及 CWs 动物对植物和微生物的影响四个方面详细讨论了 CWs 动物对污染物的影响。总结了可用于生物监测的 CWs 动物的特征，并讨论了 CWs 对保护湿地生物多样性的应用。最后，对未来的研究提出了一些展望。本研究将有助于研究人员更好地理解 CWs 动物在 CWs 中的作用，并鼓励研究人员关注湿地动物的研究。
