Abstract：With the continuous development of regional urbanization， urban expansion has become a highly concerned research subject in China's urbanization process. The expansion of the urban agglomeration simulation has become a hot research issue. In the previous simulation of urban expansion， CA (cellular automaton， cellular automata) model has come to be a widely approved method with its unique advantages of simple rule and strong extensibility in simulating urban expansion. Currently the CA model is mainly used in the simulation of a single city， yet not able to get a satisfied simulation precision in a large-scale region. In this paper， we introduced the “urban flow” model into the traditional city CA model， and the space interaction is quantified and embedded in the transformation rules of CA model. This model was applied to simulate the expansion of Wuhan urban agglomeration. The results showed that our model has a higher precision compared with the traditional Logistic-CA model， which ignores the internal space forces of the urban agglomeration to urban expansion. At the same time， the urban expansion situation of Wuhan urban agglomeration in 2020 was predicted， studies have shown that the future urban expansion would focus on the edge of the central city zone.
