摘要
由于国内城市规模不断扩大,城市圈的空间协调发展及中心城市与其周边城镇可达性越来越重要。基于交通设施和区域位置的计算方法,采用空间可达性指标对栅格化的市域铁路服务区域的可达性进行计算分析比较,利用时间差值来表征市域铁路对城镇间区域内可达性的影响。以成灌铁路为例,通过提取成都和都江堰路网信息,以两地各处间联系的最短时间为基本元素,构成成灌铁路开通前后两地可达性矩阵。计算结果表明:成灌铁路对成都和都江堰两地可达性较弱的区域影响较大,成灌铁路站点位置对两地可达性的影响呈现明显的分区特性。
Due to the further development of domestic cities,the coordinated development of metropolitan space and the accessibility between central cities and surrounding towns are becoming more and more critical.Based on the calculation method of traffic facilities and local location,this paper uses the spatial accessibility index to calculate and compare the accessibility of grid-based regional railway service area.It uses the time difference to characterize the impact of local railways on inter-city accessibility.Taking the Chengdu-Dujiangyan Railway as an example,by extracting the information of Chengdu and Dujiangyan road network,this paper considers the shortest time between the two places as the essential element to form the accessibility matrix before and after the opening of the Chengdu-Dujiangyan Railway.The results show that Chengdu-Dujiangyan Railway has a significant influence on the weaker accessibility in Chengdu and Dujiangyan,and the location of the Chengdu-Dujiangyan Railway stations influences of the availability of the two cities in a zonal characteristic way.
