杭州市城市轨道交通优势区域的时空变化

Temporal and Spatial Changes in Urban Rail Transit of Advantageous Areas in Hangzhou

选择杭州市地铁站点网络,使用复杂网络与空间格局分析方法,研究城市轨道交通优势区域的时空变化特征,对认识地铁客流量分布及城市格局的演变具有重要意义。结果表明:(1)地铁站点客流量与地铁站点中心度指标具有显著的正相关关系,站点中心度指标可部分预测站点客流量;(2)随着地铁网络的扩建,具有中心度优势的站点不是一成不变的,具有中心度优势的站点往往具有大地铁客流量的特征;(3)在总体上均呈现东西南北低,中部区域高的分布趋势。以杭州铁路西站和未来科技城为主的城市西部区域将会成为杭州的重要发展区域。各阶段站点网络在空间上均呈现显著的高值集聚特征。对于中间中心度,高值集聚区与凤起路和延安路交叉口区域、火车东站区域有紧密联系;对于接近中心度,高值集聚区以凤起路和延安路交叉口为源点,呈不断向周边各方向扩张的趋势。上述区域与目前杭州市地铁客流量居前的站点区域高度吻合。

In this work,the Hangzhou subway station network is taken as an example and complex network and spatial pattern analysis methods are used to study the temporal and spatial characteristics of urban rail transit in advantageous areas.This is of considerable significance for understanding the distribution of subway passenger flows and the evolution of urban patterns.The results are as follows:(1)the passenger flow of subway stations has a significant positive correlation with the centrality index of subway stations,and the station centrality index can partially predict the passenger flow of stations;(2)with the expansion of the subway network,the stations with centrality advantages are not static,and the stations with centrality advantages often have the characteristic of a large subway passenger flow;(3)in general,there is a trend of low flows in the east,west,south and north and a high flow in the central area.The western area of the city(Hangzhou West Railway Station and the Future Science and Technology City)will become an important development area of Hangzhou.The site network at each stage presents significant high-value agglomeration characteristics in space.For the betweenness,the high-value agglomeration area is always closely connected with two areas(the intersection of Fengqi Road and Yan’an Road and the East Railway Station area).For the closeness,the intersection of Fengqi Road and Yan’an Road is the source point of the high-value cluster area,and it shows a trend of continuous expansion in all directions.The aforementioned area is highly consistent with the current station area with the highest passenger flow of Hangzhou Metro.
