| 摘 要： | 以棕壤土为对象，采用压力膜法测定均质原状土壤样品一系列含水率和对应基质势值，分别用幂函数和Van Genuchten （1980）模型进行拟合，并与实测含水率数据进行比较。结果表明：压力膜法测定土壤水分特征曲线是可行的，所得试验结果合理，可用于土壤水分动态模拟。

| Abstract: | This research adopts pressure membrane method to determine a series of water contents in the undisturbed soil samples of homogeneous objects and matric potential value corresponding to brown soil. Simulation was made using the power function and Van Genuchten （1980） model respectively, and it was compared with the measured data of water content. The results show that the pressure membrane method for the determination of soil water characteristic curve is feasible, the experimental results are reasonable, and it can be applied to the soil water dynamic simulation. |
