摘要
文章以皖江城市带为研究对象,通过使用加权平均旅行时间、经济潜力模型及日常可达性3个主要的可达性评价指标,利用反距离加权空间插值法对数据进行可视化操作,从不同角度分析高铁的开通对皖江城市带各节点城市以及区域整体的可达性的动态变化和影响,并探讨该变化所带来的时空效应和分布格局的演变。分析得出结论:高铁的开通运营使得皖江城市带各节点城市间的可达性得到了显著的提高;高铁开通后城市的经济潜力值变化较大,信息流速度加快,产出了更大的经济效益;皖江城市带实现了一日城市带的“同城效应”,高铁为区域一体化发展提供有利的保障。
This paper takes Wanjiang urban belt as the research object,and uses the inverse distance weighted spatial interpolation method to visualize the data by using three main accessibility evaluation indexes:weighted average travel time,economic potential model and daily accessibility.This paper analyzes the dynamic change and impact of the opening of high-speed railway on the accessibility of node cities and the whole region in Wanjiang urban belt from different angles,and discusses the time effect and the evolution of spatial distribution pattem brought by this change.The results show that:the opening and operation of high-speed railway has significantly improved the reachability between the node cities of Wanjian urban belt;After the high-speed railway is opened,the economic potential value of the city changes greatly,and the speed of information flow is accelerated,and greater economic benefits are produced;The Wanjiang urban belt has achieved the"one day urban belt"effect,and high-speed rail has provided favorable guarantees for the development of regional integration.
