Abstract: The Underground Logistics System (ULS) is an important content of urban underground space planning, as well as one of necessary elements especially in new cities and districts. This paper defines the deep ULS and analyzes the necessity of its planning and construction from the perspective of the vertical planning principles on underground space, the challenges from sharply increasing logistics volume and spatial constraints which would be faced by newly planning area, and presents suggestions on geological exploration of deep ULS. The research results are shown in the followings: most of the urban goods distribution are suitable for the ULS transportation with both dedicated networks and the networks integrating with other underground infrastructure; ULS trunk network should be located in deep underground space, while the ULS last-time delivery network with a lot of human activities can be located at medium-shallow underground zones; The critical problems of the deep ULS application including geological exploration, planning based on long-term benefits, and technical integration and innovation should be solved as soon as possible.
