Abstract: At present,Chinas high-speed railway is in the stage of rapid and all-round development.Studying the impact of high-speed railway on urban land use is of great significance to urban planning and the coordinated development of city and high-speed railway.This paper uses GIS and other technologies to extract the land use data around the opened high-speed railway stations and on both sides of the line,as well as the center of gravity of construction land around some urban high-speed railway stations,and make statistical analysis and graphic comparison of the extracted results from the perspectives of different space,city type and opening time.The results show that high-speed railway can affect urban land use by promoting the transfer of various types of land to construction land;the impact of high-speed railway on the land use around the station is greater than that on both sides of the line;the impact of high-speed railway on urban land use varies according to the type of urban scale,the impact on the land use around the station is generally characterized by the greater the urban scale,the greater impact it will have,and the impact on the land use on both sides of mega cities,mega cities and county lines is greater than that of large and medium-sized cities;the impact of high-speed railway on urban land use is delayed in time,and attenuated in space.
