The erosion characteristics of soil with high content sands were studied by means of the measures of farmland test and runoff plot respectively. The results were as follows: The quantity of soil erosion from the surface of farmland was much less silting quantity in the ditches, the later was 47.3~56.6 times larger than the former. The quantity of soil erosion from runoff plot can not reflect the erosion characteristics of high content sand areas. There were close relationship of precipitation, runoff, plant coverage and soil silting quantity.
