香港城市高空绿化实践

Practice of Urban Skyrise Greening in Hong Kong

建设绿化设施是缓解城市热岛效应,改善城市热环境舒适度进而提升城市人居环境的有效措施。作为典型的紧凑型发展大型城市——香港城市建成区内可用于城市绿化建设的地面层空间十分有限。因此,包括绿化屋顶与绿化墙面在内的城市高空绿化(urban skyrise greening)设施建设对香港城市气候环境控制的作用便显得尤为重要。对香港城市高空绿化实践现状及经验进行了简要综述,旨在为国内大型城市高空绿化设施推广建设提供相应借鉴。

Constructing greening facilities is one of the most essential measures of mitigating urban heat island effect, improving urban thermal comfort condition and optimizing the urban living environment. As a typical high density megacity, Hong Kong has limited ground space for urban greening construction in its urban built-up area. Therefore, urban skyrise greening（e.g. green roofs and green fa？ades） plays an important role on urban climatic environment controlling. This paper provides a brief review of the skyrise greening practice and implementation experience, which can be used as reference for the skyrise greening promotion and construction of large cities in China.
