摘要
本项研究借用航空立体测量的方法，通过在航片判读仪上建立航空影像立体模型，测量淤地 坝中的泥沙淤积量，进而推算出小范围流域中的土壤侵蚀量，为全面开展黄土高原的土壤侵蚀量 的测量寻找一条精确有效又切实可行的途径。
The amount of silt deposit behind the dam was measured with the airborne images stereo model on the aerophoto interpreter. Based on the aerial stereo survey, and the amount of soil erosion was calculated for small river basin. This study found an accurate, effective and practical method for the comprehensive soil erosion survey on the Loess Plateau,
