Research on the Rule of Railway Network Expansion in the Northwest Region Based on GIS

摘要

With the implement of the 13th Five-Year Plan and the Belt and Road Initiative, there will be a new railway construction cycle. Considering the influence that the density of railway network and population have on regional economic, a reasonable arrangement of the railway expansion gains its' necessity. To meet the demands of social development and the railway network expansion law it needed, the northwestern region was taken as an example in studying the development law of each province by doing correlation analysis on the railway density, the population density and the Per Capita GDP. A corresponding formula was thus put forward through the analysis, the density of railway network in 2020 was analyzed adaptively, and the change graphs of railway density were drawn by way of GIS. After taking into account the policy, economic and other factors together as a whole, the result shows that the 13th Five-Year Plan of the railway of Northwest provinces is coincident with the basic rule with a little ahead of the economy level.
