通过调研获取皖江城市带各市区内公路客运联系数据,从社会网络视角,分析皖江城市带区内公路交通联系的网络特征,并结合各市区内相互作用强度的现状及历年的变化,预测其今后经济联系的主导方向,为区内公路交通联系方向的预测提供参考,从而提出区内公路交通空间组织的优化建议。结果显示:皖江城市带区内公路交通网络密度较高;根据区内相互作用强度现状,形成了合肥市主中心,芜湖市副中心和安庆市区域性中心及"东西轴线"和"南北轴线"的经济联系格局;城市间的相互作用强度不断增长,但增速不一,总体位序变化较小;今后区内公路交通空间组织方向是沿"东西轴线"和"南北轴线"发展、围绕区域中心完善并加强"两翼"建设。

Based on the investigated data of regional road passengers,this paper uses social network method to analyze the network characteristics of regional road traffic's contact in the city-cluster along the Yangtze River in Anhui Province.Combining with the current situation of regional interaction strength and its changes over the years,the article predicts the dominant direction of its economic links in the future in order to provide reference for predicting the direction of regional traffic links,and puts forward some recommendations for optimizing the spatial organization of regional road traffic.The results are shown as follows.(1)The regional road traffic's contact network has a high density.(2)On the basis of current interaction strength,it formed an economic contact pattern of three centers and two axes,i.e.,Hefei as the main center,Wuhu as a sub-center,Anqing as a regional center as well as"east-west axis"and"north-south axis".(3)The interaction strengths in the cities of researched area grow at different speeds,but their sequences change less.(4) The direction of traffic spatial organization in the future will develop along the"east-west axis"and"north-south axis",optimize the traffic around regional centers and strengthen the traffic in"two-wings".
