摘要
选择银川市西夏区应用频度较高的5种城市绿化树种(国槐、河北杨、合欢、云杉、垂柳)为材料,对树冠下、空旷地的空气温度和湿度进行了测定,探讨其对空气温、湿度的调节作用。结果表明:与空旷地相比,5种乔木行道绿化树种具有明显降温和增湿作用。各树种对空气温、湿度的影响作用不同,空气温度变化幅度均比对照低,其降温幅度为:云杉>垂柳>国槐>河北杨>合欢;空气湿度变化幅度均比对照高,增湿幅度为:云杉>国槐>合欢>河北杨>垂柳。
Temperature and relative humidity adjusting effects of several urban planting tree species in Yinchuan were investigated during July to October in 2007. The results showed that all five tree species tested had significant temperature and relative humidity adjusting effects, compared to the control, but the effects were different with species. The rank for the effect of decreasing air temperature was Picea asperata〉 Salix babylonic〉 Sophora japonica〉 Populus hopeiensis〉 Albizzia julibrissin. The effect of increasing air relative humidity was in the order of P. asperata〉 S. japonica〉 A. julibrissin〉 P. hopeiensis〉 S. babylonic.
