| 摘 要： | 土壤水分运动过程模拟计算的准确性取决于土壤水分运动参数的精度，因此正确确定土壤水力参数成为一项重要任务。自由点源入渗方法是依据稳定点源入渗公式发展而来，其准确性缺乏验证。该文通过试验资料，对该方法进行了评估，结果显示该方法可以用于土壤水力参数的确定。

| Abstract: | Simulation model was used to predict soil water movement processes. The accuracy depends on the accuracy of soil hydraulic properties, thus, it is important to estimate soil hydraulic properties accurately. Without restrict point-source infiltration method was developed based on steady point-source infiltration function, and its accuracy was still not evaluated. In the paper, the steady point-source infiltration experiment was conducted, and the method was evaluated based on the experimental dada. The results indicate that the method can be used to estimate soil hydraulic properties. |
