Abstract: Taking the areas of 800 m surrounding Xi’an Metro Line 2 as research object, the Google Earth’s high-resolution images in 2005, 2011, and 2017 were used to obtain land use data. The impacts of rail transit construction on land use were analyzed, and a prediction of land use transformation was made based on the CA-Markov model. Results showed that: (1) The construction of urban rail transit accelerated the transformation of land use types. Low-density and low-income lands, such as agricultural land and forest land, were converted to high-density and high-income lands, such as residential land. (2) Changes of station types mainly occurred in the beginning of operation phase of the rail transit and the station types were transformed to characteristic ones gradually. (3) The results predicted by the CA-Markov model revealed that the proportion of traffic facilities and the secondclass residential lands around the metro stations would increase in the future, while the proportion of the third class residential and industrial lands would decrease. In conclusion, land use types around the metro stations were relatively scattered around rail transit system and some metro stations were not well integrated with their surrounding buildings. Therefore, land use types around rail transit need further optimization to obtain optimal land use pattern and maximum land revenue.
