【摘要】：构建了一个利用"时间—空间图"来分析区域时空压缩的方法框架,并以京津冀城市群为对象,运用该技术研究由路网建设带来的交通可达空间变化。首先,分析通过网络抓取技术获取的各县市在公路网上的通行距离和时间数据。然后,再利用多维尺度分析算法将节点之间的邻近关系转化成几何关系,生成拟合可达关系的时空图,并检验拟合误差。最后,利用分层聚类划分区域城镇体系内部层域结构,利用空间统计方法来分析各聚类的水平位移平均方向、平均距离和圆方差。最后,以区域可达性均衡发展为出发点,给未来京津冀城市群交通网络建设公平发展提出政策建议,并给京津冀城市群未来的一体化发展提供分析基础。
[Abstract]:In this paper, a method frame of using "time-space map" to analyze regional space-time compression is constructed, and taking the Beijing-Tianjin-Hebei urban agglomeration as an object, using this technology to study the change of traffic accessibility caused by road network construction. This paper analyzes the traffic distance and time data of counties and cities on the highway network obtained by network grabbing technology. Then, using the multi-dimensional scale analysis algorithm, the adjacent relations between nodes are transformed into geometric relations, and a spatio-temporal map to fit the reachable relationship is generated. Finally, the hierarchical cluster is used to divide the inner layer structure of the regional urban system, and the spatial statistical method is used to analyze the average direction of horizontal displacement, average distance and circular square difference of each cluster. Finally, Taking the balanced development of regional accessibility as the starting point, this paper puts forward policy recommendations for the future fair development of traffic network construction of Beijing-Tianjin-Hebei urban agglomeration, and provides an analytical basis for the future integration development of Beijing-Tianjin-Hebei urban agglomeration.
