摘　　要：为了满足林区道路的建设要求,许多新的技术与方法被引入道路选线中来。该文主要闸述了基于3S技术的道路选线问题。遥感技术(RS)帮助设计人员全面了解沿线地形条件、植被覆盖状况等,为选线和以后的施工创造良好的条件;全球定位系统(GPS)主要用于提供准确的、高精度的勘测数据;以RS和GPS为信息源,利用地理信息系统(GIS)的空间分析和模拟能力,选择出最优的路线。尽管基于3S技术的选线目前还存在一些数据格式不统一、三维模拟困难等问题,但是利用该方法可以比较准确地选出最优的路线,能大大缩短工期,减少外业工作量,提高工作效率,减少投资。To meet the demand of building modern roads,new technologies and methods are applied to select the optimal routes of roads in forest area.3S technologies (RS,GPS,GIS) applied in route selection are studied in this paper.RS (remote sensing) technology can help designer understand the condition of terrain and vegetative cover,and create conditions for the route selection and road construction.GPS (global positioning system) is used to provide accurate and high-precision surveying data.The optimal routes could be selected by spatial analysis and modeling capabilities of GIS (geographic information system).Although some problems still exist in the route selection based on 3S technologies,such as data formal and 3D simulation,it can accurately select the optimal route,shorten working period,reduce outdoors workload,improve work efficiency and reduce investment.
