Based on the development background and characteristics of rail transit in Nanjing city, the residence, public utilities and manufacture land information are extracted, especially the commercial land within 2000 meters along the first urban rail transit. Then these land information is explored and the latent influences of the rail transit are analyzed, so the relationships between the rail transit and land use are discussed.
