本文通过野外定位试验研究了黄土高原水蚀风蚀交错带典型区域陕西神木县六道沟小流域沙柳、柠条林地土壤水分状况。该区域主要灌木林地土壤水分亏缺严重。在沙柳林地,天然降水的补给深度约为0—100cm土层.土壤干层范围为0—480cm,在柠条林地,天然降水的补给深度约为0—200cm土层,土壤干层超过600cm,土壤质地、坡位等也影响灌木林地土壤干化层分布。

The experiments were carried out at Liudaogou Catchment, Shenmu county, Shaanxi province, which is the most serious erosion center of the wind - water erosion crisscross region. In this paper, soil water content of the Salix psammophila and Caragana korshinskii was studied. It's the typical water shortage region. In the shrub land of Salix psammophila, the recovery depth was 0 - 100cm and the dry layer appeared at 0 - 480cm, in the shrub land of Caragana korshinskii, the recovery depth was 0 - 200cm and the dry layer appeared at 0 - 600cm in the vertical direction. Soil texture and slope locality also affected the dry layer distribution in the shrub land.
