The influences of piled soil under artificial and mechanical silt-eliminating on soil erosion factorssuch as infiltrative ratio of soil, runoff,anti-erosibility and anti-scourability were mainly studied. Itwas pointed that the piled soil under artificial silt - eliminating has a higher soil inflitration, littlerunoff, greater ability of anti-erosibility and anti- scourability and little erosion intensity,But, thesecharactreistics of the piled soil under mechanical silt-eliminating are completely contrary to that onesunder artificial silt-eliminatipg.At last, the advantages and disadvantages and land use of the two dif-ferent ways were discussed.
