摘　　要：研究了不同成坪处理的佛甲草覆盖对盛夏屋顶温度的影响。结果表明:14:00屋顶裸露混凝土表面地表温度达51.6℃,全成坪佛甲草覆盖的屋顶表面温度为32.5℃,相差19.1℃;半成坪佛甲草覆盖的屋顶表面温度为39.7℃,与裸露混凝土地表温度相差11.9℃。裸露混凝土屋顶表面上空10cm处温度达48.3℃,全成坪佛甲草覆盖屋顶表面上空10cm处温度为44.1℃,相差4.2℃;半成坪佛甲草覆盖屋顶表面上空10cm处温度为45.2℃,与裸露混凝土屋顶表面上空10cm处温度相比低3.1℃。种植佛甲草可以改善屋顶种植区域的小气候,温度降低明显,可为房屋顶层居民营造良好的居住环境。The effects of different disposed Sedum lineare on roof temperature in summer were studied. The results showed that the temperature of bareness beton floor was 51.6℃ at 14： 00, while cover with S. lineare was 39.7℃, with 11.9℃ diffrence. The temperature of air 10cm over the bareness beton floor was 48.3℃, while all cover with S. lineare was 44.1℃, half covered 45.2℃, which was 3.1℃ lower. The microclimate of roof growth area could be improved by S. lineare, with evidence temperature decreasing. It could make a favorable habitation condition for the peak dweller.
