京沪高铁站点选址与其所在城市发展解析

Based on satellite maps and GIS software of the built area of 22 cities with high-speed train stations of the Beijing-Shanghai Line, this paper evaluates the relationship between urban spatial expansion and the station. Four indices are adopted to quantify this relationship, including urban spatial gravity center shift from 2006 to 2012, component of shift along the direction of high-speed train station, standardized component and the intersection angle between the urban spatial gravity shift and the direction of high-speed train station. Along with the field study and interview survey, the location selection of stations and urban expansion are evaluated, and the development problems of the surrounding areas of stations are identified. The paper is concluded with key elements in location selection of regional transportation facilities, in order to promote better interaction of the surrounding area of stations and cities to achieve an intensive, efficient and sustainable development.
