The system dynamics model which is called SD for short has an advantage on describing prospective sights and predicting urban land growth macroscopically, while the cellular automata which is called CA for short has an advantage on simulating urban land expansion microscopically. So this paper integrates their macro and micro advantages, designs an coupling model for the urban land expansion, and also does a case study in Nantong City of Jiangsu Province. The results show that this coupling model can not only predict a good amount on urban land growth in time, but also simulate urban land expansion with a relatively precision in space, thus urban planning has a relatively scientific basis on analyzing urban land expansion in future.
