摘  要:
利用土壤水动力学原理 ,以陕西长武黄土沟壑区径流小区土壤为材料 ,用离心机法、水平土柱渗吸法及公式推导法分别对径流小区土壤水分运动参数 (土壤水分特征曲线、土壤水扩散率、土壤导水率 )进行测定 ,结果表明 :土壤水分特征曲线符合指数关系曲线 ,土壤水扩散率符合抛物线形式以及土壤导水率的表达式。

摘  要:
Based on the soil of runoff plot in the loess hilly areas,the soil hydraulic properties have been measured,which are the soil water retention curve,soil water diffusion and soil water conductivity.It can provide the base data for the study of water exchange and simulation of soil moisture movement in runoff plot of the loess hilly areas.
