Abstract: 【Objective】The ecosystem services functions of wetlands have attracted the attention of researchers world-wide. However, research regarding cognition of urban wetland ecosystem servicesis is limited. Further research and analysis of the cognition of residents concerning the ecosystem service functions of urban wetland parks and their influencing factors will provide the basis for the construction and management of urban wetland parks.【Method】Taking Huaxi Wetland Park and Xiaochehe Wetland Park in Guiyang City as examples, levels of cognition of the ecosystem services functions of urban wetlands were obtained using questionnaires. Then, factors influencing the cognition of the ecosystem services functions of urban wetlands were analyzed by multivariate regression analysis.【Result】①Levels of cognition of air purification, travel and recreation, and climate regulation were relatively high, while levels of cognition of waste disposal and aquatic product supply were relatively low. Levels of cognition of the ecosystem services functions of the Huaxi Wetland Park were slightly higher than those of the Xiaochehe Wetland Park. ②The main factors influencing the cognition of the ecosystem services of the Huaxi Wetland Park were age and occupation. While education level and income were the dominant factors affecting the levels of cognition regarding the Xiaochehe Wetland Park.【Conclusion】The education levels and income of residents and cognition of the ecosystem service functions of urban wetlands were positively correlated. Residents of different regions of cities exhibited differences in the cognition of the ecosystem service functions of wetlands.
