摘要
文章以距离通达性和时间通达性两个指标分别度量中国27个历史文化名城之间的公路网络和铁路网络的静态交通通达性,采用社会网络分析法衡量27个历史文化名城之间的列车和航班发车频率的动态通达性。研究发现:郑州、济南、南京的公路距离通达性最好,在地理位置上形成"三核"结构;铁路网络中各主要历史文化名城间的时间通达性离散差异较大,铁路平均最短旅行时间的空间分布格局呈现出由中东部地区向西南地区和东北地区逐渐递增的圈层结构;铁路联系程度比较高的城市之间整体呈现出"β"形状,北京是铁路网络中的核心节点,成渝两地、济南和青岛等具有明显的旅游地双核结构;远距离城市航空联系频繁,昆明和成都是航空网络中的关键节点,北京、上海、广州、昆明的航空联系密切,在空间上构成一个"梯形"结构;主要历史文化名城的整体综合交通通达性较好,北京、上海、南京、武汉、杭州、郑州和济南的综合交通通达性最优。
distance accessibility and time access are used to measure the static traffic accessibility between the highway network and the railway network of the 27 historical and cultural cities, social network analysis is used to measure the dynamic accessibility of train and flight departure frequencies between major historical and cultural cities The conclusions of the article are as follows： the highway distance of Zhengzhou, Ji＇ nan and Nanjing is the best, and the ＂three cores＂ structure is formed in the geographical position ;The time difference between the major historical and cul- tural cities in the railway network is greatly different, The spatial distribution pattern of the average shortest travel time of the railway shows a gradually increasing circle structure from the Middle East to the southwest and Northeast;the cities with relatively high degree of railway connection show a＂β ＂shape, and Beijing is the core node of the railway network. There are obvious dual core structures in Chengdu, Qingdao, Ji＇ nan and other places ; the long-distance urban air connections are frequent. Kunming and Chengdu are the key nodes in the aviation network. The air links between Beijing, Shanghai, Guangzhou and Kunming are closely related, forming a trapezoid structure in space ; the overall comprehensive traffic accessibility of the major historical and cultural cities is better, and the comprehensive traffic accessibility of Beijing, Shanghai, Nanjing, Wuhan, Hangzhou, Xi＇ an and Changsha is the best.
