Modern urban road systems often bring environmental problems and affect the quality of life of residents. The main roads in the south of Rotterdam face problems with lack of greenery, heat island effect and flash flooding. These problems have had a negative impact on the well-being of residents, and have also caused the road ecosystem to fail to provide better ecological benefits for the city. This thesis aims to explore the potential of main roads in improving ecological benefits and quality of life through the concept of ecosystem services. The purpose of the research is to use the arterial network to create urban ecological corridors, support for healthy living, and climate-adaptive infrastructure. Through the determination of the ecological value of the arterial network and its spatial quality, this thesis clarifies the goals of supporting and habitat services, cultural services and regulating services provided by roads, and proposes spatial intervention strategies. The spatial intervention strategies are applied to the three streets and become different landscape schemes. The research process of this thesis shows the value and importance of the city's arterial network in improving the ecological integrity of the city and the well-being of residents.
