壤中流模型研究的现状及存在问题

对国内外壤中流模型与模拟进行了较为系统的介绍，并针对这些模型提出了一种壤中流模型分类的方法，即根据模型所依据的主要原理将壤中流模型分为三大类：１）Ｒｉｃｈａｒｄｓ模型；２）动力波模型；３）贮水泄流模型．Ｒｉｃｈａｒｄｓ模型又可分为一维Ｒｉｃｈａｒｄｓ模型、二维Ｒｉｃｈａｒｄｓ模型和三维Ｒｉｃｈａｒｄｓ模型；贮水泄流模型又可分为动力贮水泄流模型和Ｂｏｕｓｉｎｅｓｑ贮水泄流模型．同时，将这３类模型进行对比，指出了它们各自优点和不足．

Current situation and existing problems in research of interflow models.

Based on published studies, the models and simulations of interflow were introduced, and the way of classifying interflow models was put forward in this paper. According to the main assumptions contained in these interflow models, they could be divided into three actegories: Richards, kinematic wave and storage discharge models. The Richards models were further divided into one dimensional, two dimensional, and three dimensional models, and the storage discharge models into kinematic and Boussinesq models. Meanwhile, the advantages and shortcomings of these three types of models were pointed out separately by comparison.
