| 摘 要： | 屋顶绿化是城市立体绿化的主要方式之一,能有效改善城市生态环境。本文以重庆市主城区办公楼屋顶绿化为研究对象,开展不同类型屋顶绿化的降温、增湿效应研究。研究结果表明：绿化屋顶较未绿化屋顶具有明显的降温、增湿效应,且花园式屋顶绿化降温、增湿效应高于简单式屋顶绿化类型;花园式屋顶绿化降温率（T%）为22.14%,增湿效应（R%）为81.16%,而简单式屋顶绿化降温率（T%）为3.71%,增湿效应（R%）为14.7%。本研究以期为改善城市环境,实现城市的可持续发展提供理论依据。

| Abstract: | Green roof is one of the main methods to construct three-dimensional green city as it can effectively improve the urban environment.In this paper,the green roof of office buildings in main districts of Chongqing was studied to investigate the cooling and humidifying effects of different types of green roofs in Chongqing City.The results showed that green roofs had obviously cooling and humidifying effects compared with bare roofs.The cooling and humidifying effects of garden green roofs were better than simple green roofs.The cooling and humidifying rates of garden green roofs were 22.14% and 81.16%,while simple green roofs were only 3.71% and 14.7% respectively.In order to improve the city environment,this research provides theoretical basis to achieve city sustainable development. |
