摘　　要：随着高铁的快速发展和不断完善,高铁沿线城市扩张问题备受关注。高铁的建设和运营对沿线城市的经济、社会和环境产生了深远影响,其中城市扩张是一个重要方面。基于空间句法的扩张强度指数(SS-EII)是从城市扩张的驱动力方面进行计算的,该指数不仅考虑了城市扩张的面积变化,还考虑了交通对城市扩张模式、方向的影响。本研究选取兰新高铁沿线的8个主要城市为研究对象,分析高铁开通前后的扩张强度指数,探讨期间的城市增长趋势、社会经济发展及城市竞争力等特征。结果表明:兰新高铁沿线城市的城市扩张程度较大的为兰州市、哈密市和吐鲁番市,扩张程度中等的是张掖市、酒泉市、嘉峪关市和乌鲁木齐市,西宁市的扩张程度最小。With the rapid development and continuous improvement of high-speed rail,the urban expansion of cities along the high-speed rail has attracted much attention.The construction and operation of high-speed railways have had a profound impact on the economy,society and environment of cities along the routes,of which urban expansion is an important aspect.The expansion intensity index(SS-EII)based on spatial syntax is calculated from the driving force of urban expansion.This index not only takes into account the area changes of urban expansion,but also considers the impact of transportation on the pattern and direction of urban expansion.This paper selects eight major cities along Lanzhou-Urumqi High-speed Railway as the research object,analyzes the expansion intensity index before and after the opening of the high-speed railway,and explores the characteristics of urban growth trends,social and economic development,and urban competitiveness during the period.The results show that the cities along Lanzhou-Urumqi High-Speed Railway have a greater degree of urban expansion are Lanzhou,Hami and Turpan,while those with a medium degree of expansion are Zhangye,Jiuquan,Jiayuguan and Urumqi,and the city with the smallest degree of expansion is Xining.
