摘　　要：该文着重研究了人工与机械两种不同清淤方式的堆土对土壤入渗率、地表径流、抗冲性、抗蚀性等土壤侵蚀因子的影响。指出:人工清淤的堆土,土壤入渗率高、地表径流少、抗冲抗蚀能力强,且土壤侵蚀强度小;而机械清淤则完全相反。同时还讨论了上述两种不同清淤方式的利弊和土地利用等问题。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.
