以太原市城区典型绿地植物群落——杨树片林、禾本科草坪和灌木林为研究对象，对不同绿地周边温度的空间和时间变化进行测试，并对其降温能力进行了比较。结果表明：3种绿地的温度效应均表现为午后（14：00～15：30）最明显，上午(10:00～11:30)次之；而傍晚（17：00～18：30）杨树片林和灌林木呈与前两个时间段相反的变化趋势，草坪变化不明显。3种绿地对温度的影响均呈随与绿地距离增加而减弱的趋势。杨树片林对周边空气温度的影响强度为3.55 ℃，分别是灌木林的1.48倍、草坪的2.73倍。在影响范围上，杨树片林表现也比较突出，尤其是在14：00～15：30这一时段，杨树片林、灌木林和草坪的水平影响范围分别为14 m、12 m和8 m，垂直影响范围分别为7.5 m、3.5 m和2.5 m
Three typical plant communities of urban greenbelts, poplar forest, shrub and lawn were selected and air temperature measurements taken at varying distances from selected communities and at different heights, in order to learn the spatio-temporal pattern of change of air temperature around the plant communities. The results indicate that the 3 plant communities have the most significant impact on the surrounding air temperature in the afternoon hours (14:00～15:30), followed by the morning hours (10:00～11:30). However, at dusk (17:00～18:30), there is the reverse in air temperature around the poplar forest and shrub, and no significant effect is observed around the lawns. The impact of the 3 plant communities on air temperature weakens with increasing distance away from the communities. The impact intensity of poplar forest on the surrounding air temperature is 3.55 ℃, 1.48 times that of shrubs and 2.73 times that of lawns. The poplar forest also presents a stronger influence on the surrounding field air temperature, especially in the afternoon hours (14:00～15:30). The horizontal field of influence of poplar forest, shrub, and lawn is 14 m, 12 m and 8 m, and the vertical field of influence is 7.5 m, 3.5 m and 2.5 m, respectively.
