摘　　要：运用双环法对潮关西沟林场内油松、侧柏、荒草地和农用地进行土壤水分入渗过程试验。结果表明:不同植被覆盖下的土壤入渗性能有显著差异。同林地条件下,水分入渗速率油松<侧柏;4种不同植被覆盖条件下,水分入渗速率农用地>侧柏林>荒草地>油松林地。Soil infiltration has significant difference under different vegetation coverage. The experiment can provide a theoretical basis to create and manage and protect water and soil conservation forests. Double -rings method is adopted to test soil infiltration in Chaoguan west ditch. The result showed that under the same forest land - uses, the rate of infiltration in Pinus tabulaeformis is lower than in Platycladus orientalis; under different vegetation coverage, the farmland was a little higher than Platycladus orientalis, the wild grass ground, than Pinus tabulaeformis.
