| 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。

| Abstract: | 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 orient... |
