摘　　要：本文在分析国内基础地理信息数据库现状的基础上,结合交通部最新一次的农村公路专项调查项目在重庆地区开展的数据采集、分析、建库工作,进行了基础地理信息与公路专项信息的集成应用,提出了面向对象的基础地理信息研究思路。本次研究形成了重庆市的国、省、县、乡、村多个级别的公路专题库,把传统测绘形成的基础地理成果与公路普查信息进行了空间集成,为基础地理信息的专题应用提供了很好的借鉴。Based on the analysis of the status of domestic basic geographic information database, combining the latest special investigation of rural highway proposed by ministry of transportation, data collection, analysis, database establishment conducted in Chongqing area were discussed in this paper. The integrated application of basic geographic information and the specific highway information was researched. A research idea of object-oriented basic geographic information was proposed. Different level of highway thematic database, including national, provincial, county, township and village, was established. The fundamental geographic results produced by traditional surveys are integrated spatially with highway census information, which provides a good reference for the thematic applications of basic geographic information.
