摘要
和若铁路是新疆南疆沙漠铁路环线的重要组成部分,以和若铁路沿线的7个城市为研究对象,选取通车前后2018年与2022年两个年份,运用加权平均旅行时间模型、引力模型和耦合协调度模型,分析不同交通条件下沿线地区的可达性和经济联系以及两者之间的耦合协调关系。研究结果表明:铁路开通以后,和田到若羌沿线地区的可达性平均提升了24.07%;各城市之间的经济联系也明显增强,平均增长了1.5倍左右,形成了以和田市-洛浦县为经济核心,向边缘偏远地区辐射的格局;与铁路开通之前相比,沿线地区的可达性与经济联系的耦合协调度有所改善,但整体来看协调等级变化不大。
The Heruo Railway is an important part of the desert railway loop line in southern Xinjiang.Taking seven cities along the Heruo Railway as the research object,the weighted average travel time model,the gravity model and the coupling coordination model are used to analyze the accessibility and economic links of the areas along the railway under different traffic conditions and the coupling coordination relationship between them in 2018 and 2022.The results show that after the opening of the railway,the accessibility of the areas along the Hetian-Ruoqiang line has increased by 24.07%on average.The economic connections between various cities have also significantly strengthened,with an average growth of about 1.5 times,which forming a pattern with Hetian City-Luopu County as the economic core and radiating towards remote and marginalized areas.Compared with that before the opening of the railway,the coupling and coordination degree of reachability and economic links in the areas along the line has improved,but the overall coordination level has not changed much.
