Abstract

Abstract: Rail transit is a link between cities, which can strengthen communication and cooperation among cities and promote regional economic development.Taking Lanzhou-Xining urban agglomeration as the research object,the spatial distribution law of the density and accessibility of the rail transit network is studied by using the ArcGIS software, statistics and economic geography method.At the same time,the main factors affecting the rail transit development in the region are analyzed, and the future rail transit construction plan in this area is planned.The results show that the rail transit development in central cities,Lanzhou and Xining with high road network density and accessibility is good.The rail transit construction in Lanzhou region is better than that in Xining region, and there is no through rail transit between sub center cities and central cities.According to the planned rail transit construction plan,the rail transit network layout in the future will be further optimized, which can provide the support for the "the Belt and Road" initiative node city group construction.

Key words: rail transit, accessibility, space layout, GIS, the Belt and Road
