摘要
NAM模型是概念性的降雨-径流模型,其主要参数的精度一直是制约其扩展应用范围的重要因素。中间参数通常用率定的方法反算得到,其精度与反算方法直接相关。基于NAM模型基本原理与特点,对模型尤其是参数率定的发展与研究现状进行了总结,指出采取多种反演方法组合,结合多目标反演进行参数率定将有效提高模型率定精度。
The NAM model was a conceptual rainfall runoff model,its accuracy of the main parameters restricted its application. Generally,the internal parameters were calculated by using the method of the calibration,and the accuracy of the method was directly related to the inverse calculation method. Based on the basic principles and characteristics of the NAM model,its current situation and the parameter calibration were summarized. Different inversion methods and combining multiple objective inversion were used to calibrate parameters,which would improve the calibration accuracy of the NAM model.
