交通网络基本信息变化统计服务

基于规则地理网格、县级及以上行政区、主体功能区、流域单元、地形单元（坡度和海拔）、经济区划等多种地理单元，统计铁路、公路的数量、里程、路网密度等变化信息；统计飞机场、火车站、港口码头及公路服务区等重要交通设施的数量、面积、密度等变化信息。

This dataset is constructed based on various geographic units, namely regular geographic grids, administrative divisions at county level and above, major function-oriented zones, watershed units, terrain units (slope and elevation), and economic zoning. It compiles statistical information on the changes of railways and highways in terms of their quantity, mileage and network density, and also counts the change-related data of key transportation facilities including airports, railway stations, ports and wharves, and highway service areas, covering their quantity, area and density.
