中国中心城市航空联系的网络结构数据集（2013）

依据中国国内航班2013年1月运营信息（不含港澳台），运用基于O-D联系网络的GIS 空间分析法，通过在大尺度数据空间内刻画每一条运营航线，获得全国通航中心城市间（不含港澳台）1586条航空联系组成的网络结构，并与按重力模型计算的空间联系进行对比，分运距区段绘制中国城市空间相互作用联系与航空联系网络结构图谱，得到中国东、中、西部及东北4区域间航空联系的网络结构与区域差异数据集。数据集包括：（1）中国154个通航城市出港航班数据（2013年1月）；（2）中国中心城市间1586条出港航班及其空间联系强度数据；（3）中国航空联系的距离衰减统计数据；（4）中国航空客流在中国东、中、西、东北四个区域的分布数据。该数据集存储为.xlsx格式，数据量为124KB。该数据集的分析研究成果发表在《地理科学》2015年35卷第10期。

Based on the operational data of domestic flights in China (excluding Hong Kong, Macao and Taiwan) in January 2013, this study adopts the GIS spatial analysis method based on the Origin-Destination (O-D) connection network. By mapping each operational air route in the large-scale data space, the network structure composed of 1586 air connections between national hub cities with air traffic access (excluding Hong Kong, Macao and Taiwan) is obtained. Compared with the spatial connections calculated by the gravity model, the atlas of spatial interaction connections and air connection network structures between Chinese cities is plotted by flight distance segments, and the dataset of air connection network structures and regional differences among the four regions of East, Central, West and Northeast China is finally developed. The dataset includes: (1) Departure flight data of 154 air-accessible cities in China (January 2013); (2) Data of 1586 departure flights between Chinese hub cities and their spatial connection strength; (3) Statistical data on distance decay of air connections in China; (4) Distribution data of China's air passenger flow across the four regions of East, Central, West and Northeast China. This dataset is stored in .xlsx format with a size of 124 KB. The research results derived from this dataset were published in *Geographical Science*, Volume 35, Issue 10, 2015.
