The urban public security system is composed of three different levels: management system, operation mechanism and technology platform. The technology platform plays a basic and supporting role in the whole system. Based on the platform of Geographic Information System (GIS) and Integrated Decision Support System (DSS), this paper studies and develops a "GIS-based Urban Public Security Emergency Decision Support System". It analyses the drawbacks of the current urban public security decision-making model, and introduces the structure framework of the system and the functions of each subsystem. A technical solution for constructing the urban basic space database quickly and efficiently is proposed, and the fusion mechanism between the system and the urban public security system is discussed. From the perspective of urban planning profession, it puts forward opinions on the problems existing in the preparation work, and analyzes the reasons for the formation of these problems. Finally, from the perspective of urban planning, this paper puts forward that the urban public safety planning is the process design. At the same time, combined with the current urban planning work, the paper puts forward the strategy of implementing urban public safety planning.
