兰州市轨道交通对城市时空格局影响初探
|
摘要
随着国内轨道交通的规划与兴建,有效提高了城市居民的出行效率,对研究城市空间演变也具有重要意义.以兰州市地面公共交通和轨道交通的出行时间以及交通路网为基础数据,运用比较分析法和最小阻抗的可达性分析模型研究轨道交通对城市时空格局的影响.研究发现,兰州市轨道交通相比地面公共交通工具出行效率提高了2.64倍,有效缩短了居民的出行时间;市区外围轨道交通站的辐射范围大于中心城区,轨道交通的建设更有利于市区外围居民.轨道交通影响下兰州城市空间结构由扁椭圆状变为近似圆状特征,城市的时空压缩效应明显;城市的空间可达性得到明显提高且分布更加均衡,有效增强了城关区、安宁区、七里河区、西固区之间的城市联系.
With the planning and construction of urban rail transit in China,the space-time distance of urban residents has been shortened effectively,which is of great significance to the evolution of urban space.Based on the time and traffic network data of Lanzhou ground public transport and rail transit,the present article studied the influence of rail transit on urban space-time pattern by utilizing the means of comparative analysis method and reachability analysis model per as minimum impedance.It was found that the efficiency rail transit was 2.64 times higher than that of ground public transport,which effectively shortens the travel time of residents.The radiation range of the urban rail transit station was larger than that of the central district,and the construction of the rail transit will be more beneficial to the peripheral residents of the urban area.Under the influence of rail transit,the urban spatial structure will be changed from flat ellipse to approximately circular,and the compression effect of urban space-time was obvious.The spatial reachability of the city is obviously improved and the distribution is more balanced,which effectively strengthens the urban connection.
