The invention discloses a virtual city model machine and an operation method thereof. The virtual city model machine can statically or dynamically acquire a large amount of information, has interactivity, actual experience and dynamic property, is easy to operate and low in cost, visually and quickly knows land utilization information, city building information, city road and pipe network information, city flowing information and other system dynamic information with flowability factor information relevance, and can simulate the reasonableness, implementation effect and the like of various building layouts before city planning and construction. By the virtual city model machine and the operation method thereof, intelligence is improved, the defect that the effect of a physical model can be achieved only when a large number of human resources, material resources, financial resources and the like are invested in actual construction is overcome, and the conventional city planning and management mode is changed; and the virtual city model machine has high simulation practicability, a short development period, low cost and a wide application range, provides convenience for a user, and is convenient to apply and maintain.
