摘要:
 在广州市大力推广屋顶绿化的背景下,对比了羊城创意产业园屋顶佛甲草绿化屋面与传统水泥屋面的内表面温度、外表面温度、环境气温和湿度的日变化。结果表明,佛甲草绿化屋面具有良好的隔热性能,与水泥屋面相比,具有内表面温度波幅较小,内表面最高温度较低且出现时间较晚等特点。同时,佛甲草绿化屋面可以有效降低屋顶的外表面温度,提高屋顶环境的湿度,而这种作用在12:00-15:00尤为显著,降温増湿的平均幅度分别达到15.8%和20.6%。为广州市屋顶绿化尤其是粗放型屋顶绿化的推广提供理论依据。
Abstract:
 The municipal authorities of Guangzhou promote people to build green roof in urban area.In this paper,the roof inner and outer surface temperature,air temperature and humidity were compared between green roof made by Sedum lineare and traditional cement roof.The results showed that the green roof had a good thermal insulation performance,manifested by the features of smaller varying amplitude of inner surface temperature,lower and delaying of maximum inner surface temperature compared to the control.The roof outer surface temperature decreased,and the humidity increased by greening roof.During 12:00-15:00,the temperature decreased by 15.8%,and the humidity increased by 20.6%.The results would provide a theoretical basis for green roof (especially extensive green roof) promotion in Guangzhou.
