Taking the land2use change of J inan City from 2000 to 2005, the model was app lied to analyze the influence of spatial pattern on the land2use type conversion. The results show that the model was effectively to reflect the p robability of transformation on the land2use types while they were space adjacent, and to exp lore the mechanism of the spatial pattern on the land2use type conversion and m ining the driven force of the land2use change. Lastlly, the app lication scope of the model was defined.
