摘　　要：本文利用2011―2019年国家1∶50000基础地理信息数据库中的公路网数据,以及国家统计局发布的2019年全国县级行政区人口数据,按照我国四大自然地理分区,采用路网里程、路网面积密度、路网人口密度等指标,分析我国公路网2011―2019年自然地理布局特点和变化情况,希望能够从自然地理分区的视角,为国土空间规划、公路网规划设计,以及公路与人口、经济协调发展等研究提供借鉴。Based on the road data in the national 1∶50000 topographic database from 2011 to 2019 and the population data of county-level administrative regions in 2019 released by the National Bureau of Statistics,this paper analyzes the changes of the natural geographical layout of China’s road network according to the four geographical zonings by using the indicators of road network length,road network area density and road network population density.From the perspective of physical geographical zoning,this study aims to provide reference for the research of territorial space planning,highway network planning and design,as well as the coordinated development of highway,population and economy.

关 键 词：公路网里程 路网面积密度 路网人口密度 时空变化 自然地理分区
