摘要：In this paper, firstly the dynamic visual variables are discussed. The dynamic variables of symbol include duration, change rate, change order and rhythm. Then, how to study and design the dynamic symbol is researched, the object-oriented method is used to implement the design of dynamic symbol. When designing dynamic symbol, the time frame is used to control the procedure of symbol animation by setting start time and end time. Not only the dynamic variables but also the static visual variables are introduced to show the dynamic representative form of symbol. Finally, the extensive application of dynamic symbol in visualizing map is discussed. The dynamic symbol can represent spatial position, attribute character, tense change of spatial position and attribute character in visualizing map
