摘　　要：屋面绿化是常用的建筑节能措施.对夏热冬暖地区某图书馆的屋面绿化效果实测与分析,研究屋面绿化改善室内环境的实际效果.结果显示,10月份中午12：00植物表面温度比未绿化屋面低7.8 ℃;种植模块箱底温度比未绿化屋面最大可降低23.1℃.屋面绿化对改善楼板外表面温度,减少烘烤感效果显著.当未绿化屋面昼夜温差最大为25.1℃时,绿化屋面9：00～18：00内表面温度维持在26℃左右,说明屋面绿化能够很好地稳定楼板内表面温度.Light green roof is a common building energy conservation measure, The author measured and analyzed the effectiveness of light green roof of a library in hot summer and warm winter zone and studied the actual effect of green roof in improving the indoor environment. The test results show that the plant surface temperature can be reduced by 7.8℃ and planting module bottom temperature can be reduced by 23.1℃ than the temperature of non-green roof at 12：00 in October. Green roof has a good effect of reducing the floor surface temperature and the baking feeling. When the maximum temperature difference of non-green roof between day and night is 25.1℃,the inner surface temperature of green roof is maintained at about 26℃ during 9：00-18：00. This proves that green roof also can make the roof inner surface temperature stable.
