| 摘 要： | 选择目前北京市停车场常用的11种乔木树种,在夏季7:00-18:00监测树荫下停车位的温度、地表温度、湿度、光照强度和UV-B。结果表明,各乔木树种树荫下空气温度和地表温度降低范围为0.3℃~1.25℃和3.05℃~7.26℃,相对湿度增加0.74%~5.91%,光照强度和UV-B屏蔽率达30.62%~82%和29.45%~78.61%。11种树种中,白蜡、臭椿的各项指标均显著高于其他树种,可以作为停车场绿化优先选用的树种。

| Abstract: | Eleven tree species commonly planted at parking lots in Beijing were chosen to monitor air temperature, surface temperature, air relative humidity, light intensities and UV-B under the trees between 7 am to 6 pm in the summer. The results showed that the air temperature and surface temperature were lower by 0.35℃~1.25℃ and 3.05℃~7.26℃, respectively; the air relative humidity was higher by 0.74%~5.91%; the light intensity and UV-B shielding effectiveness reached 30.62%~82% and 29.45%~78.61%, respectively. Among the eleven tree species, the above indicators for Fraxinus pennsylvanica and Ailanthus altissima showed significantly higher compared with others, which can be used at priority species for parking lots. |
