Abstract: Wetlands are a special ecological complex with a variety of functions between terrestrial and aquatic systems. Aquatic invertebrates are an important group of biotic communities in wetland ecosystems and are important participants in wetland material cycling and energy flow. Their community characteristics and spatial distribution can reflect many characteristics of wetland. In this paper, we summarized the structure and influence factors of aquatic invertebrates, as well as the aquatic invertebrate composition, and the structural characteristics of aquatic invertebrates in different types of wetlands. We also discussed the influences of environmental factors including abiotic factors (e.g. sediment, temperature, hydrology, dissolved oxygen, pH, phosphorus and nitrogen, etc.), biotic factors (e.g. vegetation, competition and predation) and anthropogenic disturbances on community structure of aquatic invertebrates. Finally, we outlined the problems and the prospects of aquatic invertebrate research in wetland ecosystems.
