| 摘 要： | 水力传导度表征土壤对水分流动的传导能力，是计算土壤水分运动的一个重要参数，反映非饱和土壤的导水率随含水率或基质势的变化关系。该文采用TS-4型土壤水力传导度测试系统分别对两种土壤进行了3次试验，结果表明:自动测定系统具有方便快捷、精度较高的特性，为实验室模拟非饱和土壤水运动参数测定试验提供了一种有效的方法。

| Abstract: | Hydraulic conductivity is the conduct capacity of water movement in soil；it is an important parameter to reflecting the relationship of unsaturated soil hydraulic conductivity with water content or matric potential.Two kinds of soil tests carried out three times by using TS-4 type soil hydraulic conductivity test system.The results showed that the automatic measurement system had properties of convenient and efficient，high precision.It provides an effective method for laboratory simulation of unsaturated soil water movement parameter determination experiment. |
