英文摘要：

According to the practical experience, the paper represents an urban planning platform （SUPlannlng） based on simulation, the corresponding architecture and technical way of assistance decision support system. At the same time, it gives some ways to solve the key technique. This paper illustrates several creative points integrated with practical development： database management and multiplayer inter active operation on city real time three- dimensional information; three - dimensional assistant examination and approving of layout design and building database; rapid modeling methods of multi data sources; layout project examination and approving and public participation; real time analysis of layout influence. In conclusion,provides more advanced information technology methods that are needed in city layout management. City layouts＇ effective management, scientific decision - making and smooth communication are becoming into realities by these methods.
