To quantify the effects of urban wetlands on temperature and humidity of ambient environment, five urban wetlands with different shapes and surroundings were selected in Daqing City, and the air temperature and relative humidity were investigated in spring, summer and autumn using small-scale quantitative measurement method. The results indicated that the urban wetlands with different shapes all could decrease the temperature and increase the humidity, with the effect being strongest in summer, followed by in spring, and the smallest effect in autumn. The shape of the urban wetland had significant effect on temperature and humidity, which decreased in the order of irregular-shaped wetland > regular-shaped wetland (subcircular-shaped wetland, subcuboid-shaped wetland) > long-shaped wetland. The diurnal variation of temperature and humidity was influenced by the ambient temperature, namely the effect of wetlands was weak in morning and evening, but strong at noon. The maximum effect occurred at12:00-14:00 in spring and autumn, and at 14:00-16:00 in summer.
为了量化城市湿地对周边环境温度和湿度的影响，在大庆市选取了5块形状和周边环境各异的城市湿地，采用小规模定量测量方法对春、夏、秋三季的气温和相对湿度进行了调查。结果表明，不同形状的城市湿地均能降低温度、增加湿度，其中夏季效果最强，其次是春季，秋季效果最小。城市湿地的形状对温度和湿度有显著影响，其影响程度由大到小依次为不规则形状湿地＞规则形状湿地（近似圆形湿地、近似长方体湿地）＞狭长形状湿地。温度和湿度的日变化受环境温度影响，即湿地在早晚的作用较弱，中午较强。春季和秋季的最大作用出现在12:00 - 14:00，夏季出现在14:00 - 16:00。
