江苏省高速公路交通流空间运输联系特征分析

Study on Transportation Connection Characteristics of Jiangsu Province Based on Expressway Traffic Flow

空间运输联系能够反映区域之间的经济联系,是分析区域之间相互作用的重要依据。基于高速公路交通流数据,文章构建了空间运输联系强度模型,对江苏省空间运输联系特征进行了研究。研究结果表明:各城市空间运输联系总强度差异明显并呈现出"南高北低"的特点;各城市趋向于区域经济中心城市取得首位联系;苏南地区空间运输联系的区域化特征显著。

As an important indicator of regional interactions, spatial transportation connection could reflect the economic relations of geographical units.Thepaper establishes the transportation linkages strength model to extract the regional spatial transport connection characteristics of Jiangsu province based on freeway traffic flow. The results show that spatial transportation connection exhibits significant regional differences and spatial transportation connection strength ishigher in south Jiangsuandlower in north Jiangsu; cities make the first contact with regional economic center; regionalizationcharacteristics of spatial transportation connection of South Jiangsuare significant.
