摘要
选择在植物降温作用最为明显的夏季,以重庆市不同屋顶绿化类型为研究对象,比较研究简单式和花园式屋顶绿化的降温增湿效应。结果表明,简单式屋顶绿化、花园式屋顶绿化对室内温度的平均降温程度分别为1.75℃、4.35℃;与无绿化屋顶相比,简单式、花园式屋顶绿化对屋顶环境的平均降温程度分别为2.55℃、9.81℃,增湿效果分别为5.01%、21.19%,降低地表温度的程度分别为7.93℃、18.14℃。表明屋顶绿化具有显著的降温增湿效应。
This paper take different roof greening in Chongqing as research object ,and choose the most obvious plant effect season summer as research time ,so as to compare the cooling and humidifying effects of simple and garden roof greening modes .The results show that simple roof greening and garden roof greening′s average temperature indoor is 1.75 ℃and 4.35 ℃respectively;compared with blank roof ,simple roof greening and garden roof greening′s cooling degree is 2.55 ℃,9.81 ℃respectively ,and the humidifying effects are 5.01%,21.19%;the sample and garden roof greening′s cooling degree of the surface temperature is 7.93 ℃and 18.14℃respectively.The results indicate that green roofs have significant ecological effect .
