摘　　要：纳林川布尔洞流域位于黄河中游砒砂岩分布区,由于砒砂岩抗侵蚀能力差,而且当地夏季降雨集中,导致砒砂岩发生严重的水土流失,侵蚀沟边线持续不断地后退。本文运用高分辨遥感及G IS方法对当地砒砂岩侵蚀沟边线的蚀退距离进行了计算,并对蚀退影响因素进行了综合分析。Buerdong gulley is located in pisha sandstone distribution area along the middle reaches of the Yellow River. Strong erodibility of pisha sandstone together with concentrated precipitation have caused the continuous erosion of the edge lines of the slope, affecting the living conditions of local residents. Therefore, it is necessary to study the erosion rule of pisha sandstone. In this paper, the erosion distance of pisha sandstone was calculated by using remote sensing and GIS technology, and the effecting factors were analyzed.
