通过对黄土丘陵区纸坊沟流域土壤水分对植被恢复影响的研究，得出以下结论：（1）草地土壤含水量高于灌木地，灌木地土壤含水量高于荒地;（2）油松使土壤干层变浅，通过带状造林，可以提高刺槐林地的含水量。（3）土壤干化程度与植被和造林密度有关。（4）自然植被也可能造成土壤层的干燥。
According to the study on the effect of soil water on rehabilitation of vegetation in Zhifanggou watershed of loess hilly region,the following conclusions are drawn:(1)The content of water in grass ground is higher than in shrub ground and the shrub ground's is higher than aboreal ground's.(2)The pine(pinus tabulaeformis)makes a lighter dried soil layer.By means of strip forestation,the content of the water of Robinia(Robinia pseudoacacia)ground can be improved.(3)The degree of the dried soil layer is related with vegetation and forestation density.(4)The natural vegetation may cause a dried soil layer too.
