ABSTRACT

This study focuses on Tokyo's adaptation strategy to climate change and its effectiveness, aiming at providing reference for global cities. Through an in-depth analysis of Tokyo's measures to transform the sewer system and enhance the urban ecosystem, this paper shows how Tokyo faces the challenges of climate change such as frequent extreme weather, sea level rise and urban heat island effect. In this paper, the development history, current situation and key role of Tokyo sewer system in urban drainage are described in detail, as well as the concept, current situation and measures to improve climate resilience of urban ecosystem. In this way, it reveals the actual actions and achievements of Tokyo in dealing with climate change. It is found that Tokyo has effectively enhanced the city's flood control ability by implementing the reconstruction projects of sewer system, such as building large reservoirs, popularizing rain gardens and strengthening the maintenance of drainage pipes. In addition, through urban planning, green space expansion, biodiversity protection and other urban ecosystem construction measures, the ecological resilience and carbon sink function of the city have been improved. The synergy of these strategies has significantly improved Tokyo's adaptability to climate change. The conclusion is that Tokyo's climate change adaptation strategy provides valuable experience for other cities around the world.
