The construction of smart city has provided multi-source data support for systematic cognition of the city operation, and also brought new opportunities for the urban development model. This paper explains the construction foundation of the smart city simulation model from the aspects of urban elements organization mechanism and the urban system operation representation. Then, a concrete organization of the simulation model is elaborated in the following four parts:model concept connotation, component elements, framework structure and main functions. Finally, specific application scenarios of the simulation model are discussed including urban planning scheme evaluation, urban design perception interaction and urban operation management decision.
