摘　　要：养分离子和污染物的运移是农学和环境学共同关注的研究热点。随着模拟模型的发展，模型参数的确定成为关键问题。本文综述了由BTC确定参数的方法:试错法，斜率法，概率特征法，最小二乘法，图解法，截获法，力矩法，并加以简要的述评。Knowledge of nutrient and pollutant ions transport is important from an agricultural and an environmental point of view. With the developing of various kinds of model. The determination of transport parameter became the key problem remained. This article summarizes methods of determination of transport parameter from BTC: Trail and Error,Slope Method, Statistic Property Method, the Least-squares Inversion Method, Graphic Method. Holdup Method. Moment Method.
