Soil water content and the corresponding value of tension are obtained using the device of soil water characteristic curve through testing of three kinds of soil samples from the Agricultural Eco System Experiment Station in Luancheng City,Hebei Province.Water characteristic curve is simulated using 6 kinds of models,and the relationship between soil water content and tension is expressed by the six different models.Through comparison of the water content simulated and observed,it is drawn that for different soil,the optimal characteristic curve model is different.For the original soil sample, the best simulation model is the model Van Genuchten.While for the disturbed soil sample,the best simulation model is the modified model Van Genuchten.
