Abstract
Introduction and background 引言及背境
With rapid proliferation of urbanization and industrailization, there has been a substantial growth in population and buildings in the developed cities. In most instances, the opportunity cost for the concentration of tall buildings on a limited land is the provision of quality greenery and public open spaces. Besides, such concentration subsequently triggers tremendous environmental threats, such as urban heat island effect, low wind speed, pollutions and air quality degradation. Conversely, the importance of a quality and livable environment as well as the need of balanced urbanization and nature is also being recognized. Skyrise greenery, such as vertical planting, rooftop gardens and sky gardens, are then emerged to provide an alternative solution of co-existence between building and vegetation within the same domain.
隨著都巿化和工業化的激增，在已發展的城巿裡，人口和建築物都大幅的增長。在大多數的情況和有限的土地上，高樓大廈只可集中地建設，其機會成本，就是優質的綠地和公共空間被犧牲。同時，這種集中的發展，也引發對環境的嚴重威脅。例如城巿熱島效應、低風速、污染和空氣質量劣質化。另一方面，優質及可居的環境，要求平行都巿化和自然的需要也被確認。空中綠化的出現(例如垂直大,一綠化、天台花園和天空花園先後出現)，作為處理在同一個範圍裡，建築物和植物並存的一個另類的解決方案。
