摘要

Jiangjiagou valley is an area with most developed debris flow valleys in China. Based on Jiangjiagou valley, according to the difference of magnetic characteristics in sediment and soil, this paper studied quantitatively the sediment sources. The results showed that sediments mainly came from landslide debris, accounting for 97.56%; the contributive ratio of grassland and sloped farmland for main channel sediments was very low. It was accordance with using 137Cs tracer technique. But there are still some limitations, and further strengthen research and discussion with combination of 137Cs isotope tracing.
