- 摘要:
- 以晋西黄土区为研究对象，研究黄土区土壤的水分入渗规律。为了更好地研究不同环境因子（尤其是立地、坡度、植被）对于土壤入渗性能的影响，在不同的土地利用条件下，对不同地貌部位进行了野外入渗实验。研究结果表明土壤渗透率随时间的变化规律是：在开始时渗透率最大，继之随时间而降低；林地累计入渗量明显高于其它用地。此外，林地的土壤入渗速率为最优，道路路面为最小。研究表明Philip方程能够很好地对当地土壤入渗进行模拟。
- Abstract:
- Soil moisture infiltration is studied in the Loess Area of Shanxi Province. In order to research the effect of different environmental factors (especially site, slope and vegetation) on soil moisture infiltration, infiltration observation is done in different topographical features position and land use. The results show the law of soil moisture infiltration with the time is that the initiation infiltration speed rate is the highest in the beginning, then it gradually fall. The infiltration speed rate of the shrub stands is the highest. The filtration speed rate on surface of road is the lowest. Based on the study, soil moisture infiltration can be simulated well by Philip soil moisture infiltration model.
