摘　　要：文章以内蒙古自治区准格尔旗为研究区域,以遥感影像和地形图作为基础数据源,以ArcGIS软件为操作平台,提取研究区侵蚀沟道及其长度、面积和纵比降等参数。结果表明:研究区内沟道长度(主沟长度,不含支沟)500m以上、汇水面积不大于5km2的侵蚀沟道共有10312条,总长度为7552008m,总面积为2381.40km2。侵蚀沟道长度主要集中在500～1000m范围之内,面积在10～20hm2级别内分布的最多,纵比降主要在0%～10%范围内。The paper took Zhungeer County in Inner Mongolia as the study area, Based on remote sensing images and topographic map as a data source, Extracted research area＇s eroded gully and its parmneters such as length, area and longitudinal slope by use of the ArcGIS software platform. The results showed that in the study area a total eroded gully is 10132, their length is more than 500 m （the main gully length, excluding branch ditch）, catchment area is not greater than 5 km2, with a total length of 7552008 m, with a total area of 2381.40 km2. The eroded gully length mainly concentrated in the range of 500 - 1000 m, area of most distribution in level of 10 - 20 hm2, longitudinal slope mainly in the range of 0 - 20 m.
