Since the establishment of the national land space planning system,no specific guidelines for the formulation of national land space planning for railways have been issued by relevant authorities.This paper presents a study on the preparation of national land space planning for railways.With the project"Study on National Land Space Planning for Railways in a Certain Province"as a case for study,a three-step study approach was put forward,including"establishing a project database,proposing land-use scale,and investigating spatial relationships",to guide the study of national land space planning for railways.The paper emphasized the analysis of the relationship between railways and the"Three Lines"within the national land space.Through the discussion of the study approach and methods,it aims to provide a reference for the compilation of special national land space planning for railways and offer guidance and reference for railway alignment selection.
