AbstractThis study estimates the sediment trap quantization efficiency in the Qietongliao watershed, the Dahudi
watershed and the Nansaru watershed. The results of the study show that, the decrease in the landslide ratio after the establishment of sabo dams in the three watersheds is 33.2%/year in the Qietongliao watershed, 11.2%/year in the
Dahudi watershed and 12.1%/year in the Nansaru watershed. The annual sediment trap volume is also estimated to be
1.6..104 m3 in the Qietongliao watershed, 8.1..104 m3 in the Dahudi watershed and 1.17..104 m3 in the Nansaru watershed.
