- 摘要:
- 土壤渗透特性是土壤重要的性质之一，采用双环法对黄土高原丘陵沟壑第三副区吕二沟小流域不同地形、不同土地利用方式的土壤进行渗透性测定，研究其入渗透规律。结果表明：不同土地利用类型对土壤饱和渗透率影响较大，无论是在流域的上游、中游还是下游，饱和渗透率都表现出刺槐林>草地>耕地和果园的规律。在整个流域角度分析，饱和渗透率总体表现出不明显的流域中游>流域出口>流域上游和不明显的流域右侧>流域左侧的规律；土壤饱和渗透率与含水量无关，与土壤容重和非毛管孔隙相关性较大，即土壤饱和渗透时主要是通过非毛管孔隙进行的；应用不同模型对渗透过程进行拟合，霍顿模型拟合效果较好拟合系数为0.930。
- Abstract:
- The soil permeability charateristics of the third subdivision-Lǔergou small basin in Loess Plateau hilly-gully regionis were studied with double-ring method based on field investigation. The results showed that the soil permeability coefficients were closely to different land uses, and the soil permeability coefficient of locust forest is the biggest, the coefficients in the cultivated land and orchard are the smallest. Analyzing on the whole basin, the soil permeability coefficients did not obviously presents middle reaches > downstream > upstream, and right side > left side. The soil permeability coefficients is well related to bulk density and non-capillary pores, and the soil permeability coefficients is mainly controlled by non-capillary pore. Soil permeability coefficients fitting precisions with Horton’s model are perfect and the correlation coefficient is 0.930.
