Abstract

Under the background of urban population growth and increasingly prominent urban environmental problems. Green infrastructure in line with sustainable development is considered a possible solution. This paper aims to study the application of green roofs (GR) and vertical greening systems (VGS) in densely developed cities, such as Tokyo and Singapore, and provide a reference for Hong Kong. This study believes that GR and VGS have great potential in alleviating urban environmental problems in Hong Kong and can effectively provide more green development space. At the same time, it plays an active role in alleviating the urban heat island effect, reducing air pollution and energy consumption. Currently, there are some urgent problems with the application of GR and VGS in Hong Kong, such as construction cost recovery, hidden dangers of public safety, and technical construction difficulties. In addition, this paper suggests that Hong Kong should provide more investment and support for GR and VGS in legislation and technology to promote their promotion and popularization.
