Abstract：Virtual-reality city (VR city) is one of the most important technologies in 3D urban GIS. This paper present how to establish city landscape of three-dimension

generalize the development of general situation and basic principle of city 3D simulation

and analyze two kinds of methods of the establishment of city landscape of three-dimension. Then we introduce the methods of 3D scenes of establishing dynamic simulation and real-time driving

and put forward the function

meaning and development foreground of the city landscape of three-dimension dynamic simulation technology. Finally

we summarize the possibility and direction of development of combining city 3D simulation and GIS

and give an example of city landscape of three-dimension dynamic simulation.
