摘要
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(14:005:30)最明显,上午(10:001:30)次之;而傍晚(17:008:30)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14:005:30这一时段,杨树片林、灌木林和草坪的水平影响范围分别为14m、12m和8m,垂直影响范围分别为7.5m、3.5m和2.5m。
