Research On Matter-element Extension Model Based On Entropy Method In The Linesite Of The Urban Subway Choosing

With the economic globalization,nowadays,Chinese economy is developing rapidly.With the process of urbanization boosting, the people’s requirement of the foods and clothes is also increasing day by day.increasing pressure of the city traffic.High-quality,rapid and convenient traffic environment has become a necessary requirement of the residents’ to be improved. In this context, the city put lots of money in the subways’ construction. But the high costs and risks also limit the speed and scale of the subways’ processing, the selection of station and length, affect the efficiency and social benefits. It has been put on the agenda that how to extend the benefits and satisfy the people’s demand.A reasonable plan of site selection can better coordinate the overall plan for the site layout and wiring, reducing unnecessary investment and ensuring the smooth construction of subway.In this article,according to the theory of subways’ construction and the analysis of factors that matters stations’ location,in which the entropy theory and extension theory, established index evaluation system to adapt with it, Taking the western suburbs of Xiangshan Beijing subway station line’s location for an example,it shows matter-element extension model based on entropy method in the line site of the urban subway choosing can be used.
