Abstract:Markov chain in land type conversion tendency model has been used in evolution analysis of city land quality. Through the establishment of land quality grade transfer matrix, setting quality level changes of commercial using land in Lanzhou city from 2009 to 2014 as the application case, the effect of land quality transfer matrix to land use in cities has been studied. It is showed that the construction of the transfer matrix can reflect the tendency evolution of land quality level effectively. And it can predict the future trend of city land quality in a certain extent. Further, it is the driving force of studying the evolution of land quality in the city, and can guide and promote land resources utilization in the future.
