Impact and trend of transportation accessibility on regional cohesion in the Qinghai-Xizang Plateau
As one of the largest plateau regions in the world,the Qinghai-Xizang Plateau has a wide geographical range and diverse geographical features.The development characteristics and laws of regional transportation networks are important links connecting various regions,promoting resource and personnel flow,and playing a crucial role in the research of overall regional development and regional cohesion.This article takes the Qinghai-Xizang Plateau as an example to analyze the spatial pattern and regional cohesion of transportation accessibility from 1990 to 2030,revealing the impact of transportation accessibility on re-gional cohesion,and providing a more comprehensive understanding through the perspective of spatial eq-uity.Research has found that the expansion of roads promotes overall accessibility levels.The spatial dis-tribution of regional railway accessibility is gradually becoming fair,which has a positive impact on region-al cohesion.Looking forward to the trend of regional cohesion in 2030 based on railway accessibility,in or-der to support sustainable development and balanced socio-economic growth in the Qinghai-Xizang Plateau region.In the future,we should strengthen the planning of the territorial space system of the Qinghai-Xi-zang Plateau as a unified whole,build the Lhasa Ali railway line as soon as possible,and increase the strength of the Qinghai-Xizang Plateau for Chinese path to modernization.
