| 摘 要： | 本文就六种持水模型在各吸力段的拟合度进行了比较,模型lnS=a+bθ+cθ~2+dθ~3的拟合效果最好,而模型S=aθ~(-b)和S=ae~(b4)虽然简单,但拟合效果最差。

| Abstract: | The effectiveness of modelling water retention of six soils in different fange of soil water suction was compared in the current paper. A polynomial function was the most effective model in describing the relation of ln(s) and 8 among 0 to 1500kpa. The exponential form and power form were simple but not precise, and the others functioned in between. |
