Abstract

Urbanization affects the microclimate and forms a unique urban climate environment. To deepen the understanding on the microclimate regulation function of an urban wetland, this study analyzed the influence of a suburb wetland’s urbanization process on the local climate through contrast observations of the protected wetland area and the former wetland area in Xixi wetland. Results show that the urbanization of suburb wetlands has an impact on the local microclimate and decreases human comfort, and that wetlands can effectively regulate the microclimate. The fragmentation of urban wetlands caused by urban sprawl decreases their microclimate regulation function, a decrease that is particularly evident in summer. Additionally, wetlands stabilize the microclimate in all seasons. For every land cover type in wetlands, vegetation has a better stabilizing effect on temperature, whereas a water body has a better stabilizing effect on wind speed and humidity. Meteorological conditions also affect the microclimate regulation function of wetlands. Temperature, humidity, atmospheric pressure, and wind speed influence the cooling function of urban wetlands, while solar radiation modifies the humidifying function of urban wetlands.
