Abstract: With the continuous promotion of large-scale housing construction and underground space engineering, the construction waste had increased significantly and become the largest category of solid waste production. If not effectively controlled and properly disposed, it would cause enormous pressure on the environment, thus making the city face the dilemma of besieging by construction waste. Therefore, source reduction and comprehensive utilization were the best way to control urban construction waste in the future. Taking Shenzhen as an example, the study explored the implementable strategies of reduction and comprehensive utilization of construction waste from the entire process of planning， design，construction， and resource utilization based on current situation analysis and advanced experience at home and abroad, in order to achieve urban green urban development and the construction of a zero waste city. It was expected to provide countermeasures and suggestions for reduction and comprehensive utilization of the construction waste in megacities with high intensity and high quality development.
