摘　　要：为了对林区道路的涵洞进行科学选址,本文以杭州市萧山区为研究区域,以DEM数据为研究基础,采用GIS水文分析法对DEM进行填充洼地、计算流向、计算汇流累积量、阈值筛选、叠加求交等操作,得到涵洞选址大致位置,从而进行小范围详细勘察,得到合理的涵洞选址。与传统作业模式相比,该方法能充分依据GIS理论和计算机技术科学合理地选点,从而大大减少了外业勘查设计人员的工作量,不失为一种新的探索模式。In order to scientifically locating forest road culvert, this paper takes Xiaoshan District of Hangzhou as the study area, using GIS hydrological analysis for filling DEM depressions, calculating flow direction and accumulation, selecting threshold, overlap-ping and intersecting the maps, etc. to get the location of culverts. After a small range of detailed investigation, a reasonable location of culverts can be obtained. Compared with the traditional work, this method can select the locations scientifically and reasonably based on GIS and computer technology. It can greatly reduce the workload of field survey, which can be a new exploration method.
