摘　　要：采用土壤传递函数法,对确定土壤田间持水量的点估算模型和系数估算模型进行分析研究,并用山西省太古县水均衡实验场和河南开封朱仙镇试验基地的实测资料对模型进行验证.结果表明,在土壤田间持水量的研究中,土壤传递函数法是一种行之有效的方法.The point-estimation model and coefficient-estimation model for determination of field capacity were studied by use of the Pedo-Transfer Functions (PTFs) method, and the models were verified with measured data from the field water-balance experiment in Taigu County of Shanxi Province and the sand field experimental base at Zhuxian town in Kaifeng County of Henan Province. The result shows that the PTFs method is an important method for determination of soil water content in research of field capacity.
