| 摘要: |
| 为研究不同类型屋顶绿化的温湿度日变化，选择了广东省广州市越秀区地毯式、花园式和棚架式和盆花式4种不同的屋顶绿化类型，观测和统计分析不同绿化形式的屋顶及其不同空间位置的温度和湿度的变化。结果表明，各种类型的屋顶绿化对小气候都产生了显著的效应。其中，地毯式绿化类型植被覆盖度最高，降温效果最明显，温度最低；花园式和棚架式相当；盆花式效果较差，温度较高；各个测定位置的湿度数值则与温度相反，与降温效果一致。综合温湿度结果，4种屋顶绿化类型都产生了不同程度的生态效应，其中地毯式最佳，花园式和棚架式次之，盆花式较差。 |

| Abstract: |
| For studying the diurnal variation of temperature and humidity of different types of roof greening，4 types of green roofs including carpet，garden，frame and potted flower in Yuexiu District of Guangzhou City were selected. The temperature and humidity changes in different types of green roofs with their locations were surveyed and analyzed. The results showed that various types of green roofs had a significant effect on the microclimate. Among the 4 types of green roofs， the carpet roof greening exhibited the best cooling effect with high vegetation cover. The garden and frame types were nearly the same exhibited better effect while the potted flower type was the worst of all. The humidity measured at all types of roof garden were significantly higher than that of the exposed roof. Humidity effects were ranked as follows：carpet＞garden and frame＞potted flower. In general, 4 types of roof greening had different degrees of ecological effect. Among them，carpet was the best. Garden and frame types were the secondary, while potted flower was the poorest. |
