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．
This paper presents a systematic introduction of mid-flow mid-flow models and simulations, and proposes a method of mid-flow flow model classification for these models. According to the main principles on which the model is based, mid-flow flow models are divided into three categories: 1) Richards model; 2) dynamic wave model; 3) reservoir water discharge model. The Richards model can be divided into one-dimensional Richards model, two-dimensional Richards model and three-dimensional Richards model. The water storage and discharge model can be divided into dynamic reservoir water discharge model and Bousinesq water discharge model. At the same time, the three types of models are compared, pointing out their respective strengths and weaknesses.
