“一带一路”沿线地区沿海港口与机场分布图（2018）

数据主要包括“一带一路”沿线国家和地区的主要沿海港口和机场的点位分布，数据来自Natural Earth全球港口和机场数据，依据“一带一路”沿线65国标准底图对数据进行裁剪，并对数据进行校正处理，获得沿线地区港口和机场的点位分布。本数据主要用于分析“一带一路”沿线地区重要交通设施的空间布局和主要特征，在后续研究中获取港口和机场的其他属性数据包括港口不同货种的吞吐量、进港和出港吞吐量、码头泊位数、机场乘客人数、港口和机场的航线航班数据后，可对港口和机场分布的空间分异有进一步的认识。

This dataset primarily covers the spatial distribution points of major coastal ports and airports in the countries and regions along the Belt and Road Initiative (BRI). The raw data is sourced from the global port and airport datasets provided by Natural Earth. It was cropped using the standard base map of the 65 countries along the BRI and then underwent correction processing, ultimately yielding the spatial distribution points of ports and airports in the regions along the initiative. This dataset is mainly utilized to analyze the spatial layout and core characteristics of important transportation facilities in the BRI-related regions. In follow-up studies, after acquiring additional attribute data for ports and airports—including the throughput of various cargo categories, inbound and outbound throughput of ports, the number of terminal berths, passenger volumes of airports, and route and flight data of both ports and airports—a more in-depth understanding of the spatial differentiation of port and airport distributions can be obtained.
