摘要:
通过对林地土壤水势和土壤含水量变化规律得出在降雨入渗过程中,土壤水分变化过程是零通量面发散和收敛型的相互转换;土壤含水量和土壤水势变化规律基本相同,林地10～20cm剖面水分变化受环境影响最显著,属表层急变型;30cm剖面水分变化相对缓慢为过渡层;50～100cm剖面水分变化较为一致,含水率也较为接近为稳变层.
Abstract:
The changes of soil water potential and soil moisture content of forest were analyzed,the result showed that the variety of soil water potential was the transpiration between disconvergent of zero flux plane(ZFP) and convergent ZFP in the process of rainfall infiltration,and soil moisture content was almost the same change as the soil water potential.The change of soil moisture on the section from 10 to 20 cm was the most distinct.This section was the surface leap type.And the variety on the section of 30 cm was slow,which was the transition layer.The variety of the section from 50 to 100 cm was even,and the section was near to the steady layer.
