摘要
以通达性模型和空间经济联系强度模型计算了滇桂黔地区内32个城市在2014年和2017年两个年份的铁路通达性和各城市间的经济联系,对比高速铁路开通前后的变化;研究发现:高速铁路开通可显著提高沿线城市的区域通达性,促进了多个铁路网中心城市的形成,通达性水平优化移动方向从以贵阳安顺为中心向广西东南及南部沿海移动。高速铁路开通使沿线城市交流越来越密切,贵安经济走廊、昆明、曲靖、玉溪半小时圈、北部湾都市圈等多个空间格局的初步形成,但沿线城市的通达性水平和经济联系强度存在较大的差异。
Based on the accessililit model and the spatial economic linkage strength model, the railway of the 32 cities in the Yannan - Guangxi - Guizhou region in 2014 and 2017 and the economic links between the cities were calculated, and the changes before and after the opening of the high - speed railway were compared. It is found that the opening of high - speed railway can significantly improve the regional accessibility along the route, and promote the formation of multiple railway network central cities. The accessibility optimizes the movement direction from Guiyang Anshun to the southeast and south coast of Guangxi. The opening of high - speed railways has made the exchanges along the cities more and more close. The preliminary formation of various spatial patterns such as the Gui’an Economic Corridor,Kunming, Qujing, Yuxi Half - hour Circle, and Beibu Gulf Metropolitan Circle,but the accessibility level and economic connection intensity of the line have big differences.
