摘要

城市中植物群落的降温增湿作用是缓解城市热岛效应的有效途径。选择江西财经大学麦庐园校区的乔木林、灌木丛和草坪为研究对象

对3者在小尺度范围内调节城市小气候的效应进行了定量化研究。结果表明:(1)乔木林的降温效应最明显出现在20:00(-4.00℃)

最弱是在10:00(-1.68℃);灌木丛降温效应最明显出现在8:00(-2.95℃)

最弱是在12:00(-0.27℃);草坪影响下的降温效应最明显出现在20:00(-2.31℃)

最弱是在10:00(0.38℃);(2)上午时段灌木丛的降温效应明显

灌木丛和草坪增湿效应明显;下午时段草坪降温效应变化幅度大

乔木林在下午时段增湿效应的变化幅度大;(3)乔木林、灌木丛和草坪的降温效应和增湿效应都随距离的增大而减少

温度差值和相对湿度差值在水平和垂直方向上的变化趋势基本一致。

Abstract

The cooling and humidifying effect of the urban plant community plays an important role in alleviating the"urban heat island effect".To study the effect of vegetation in regulating urban microclimate at a small scale

arboreal forest

shrubs and lawns were chosen in Mailu campus of Jiangxi Finance and Economics University.The results showed that:(1)The most significant cooling effect of arboreal forest occurred at 20:00(-4.00 ℃)

while the weakest effect occurred at 10:00(-1.68 ℃).The most significant cooling effect of shrubs occurred at 8:00(-2.95℃)

while the least effect occurred at 12:00(-0.27 ℃).The most significant cooling effect of lawns occurred at 20:00(-2.31 ℃)

while the least effect occurred at 10:00(0.38℃).(2)In morning

the cooling and humidifying effects of shrubs were great

and the humidifying effects of lawns were significant.In afternoon

the cooling effect of lawns and the humidifying effect of arboreal forest varied greatly.(3)The cooling and humidifying effects of arboreal forest

shrubs and lawns decreased as the distance increased.The changes in temperature difference were consistent with the variation in relative humidity difference at the horizontal and vertical direction.
