摘　　要：根据甘肃秦王川地区的土壤质地分布特征 ,在现场 5个点进行了积水入渗试验 ,同时采用γ透射法及张力计测定了各点的土壤水分特征曲线及非饱和导水率。在分析研究了各水分运动参数与表征土壤物理属性的(Kd/γd)和 (Kp/γd)有极显蓍相关性的基础上 ,提出了适用于该地区各类土壤质地的水分运动参数表达式。According to features of soil texture distribution in the Qingwangchuan area of Gansu province, a series of Pondinginfiltration tests were conducted to measure soil water characteristic curve and unsaturated conductivity with γ ray and tensiometer at five experimental sites.Available formula for expressing the soil hydraulic parameters with various textures were developed based on the analysis of the relations of soil hydraulic parameters with the parameters expressing the soil physical properties,K d/γ d and K P/γ d.
