Abstract: Studies on the models of root reinforcement have a history for about 40 years. From the simple limiting equilibrium model to the complex finite element model (FEM) and discrete element model (DEM) models, more than 10 types of models of root reinforcement were developed. To summarize these models of root reinforcement, not only is important for revealing the mechanism of soil reinforcement by plant roots and analyzing the stability of forested slope, but also provides a scientific guide for the future research on root reinforcement models. In this study, the root reinforcement models were summarized from two parts. The first part mainly introduced theoretical models, including Wu’s model, inclined root reinforcement model, displacement-based model, fiber bundle model, root bundle model and energy approach model, as well as the preconditions, advantages, disadvantages and the applications of the models. The second part mainly introduced numerical models of root reinforcement, including the finite element model (FEM), discrete element model (DEM) and the numerical model of forested slope stability analysis. The advantages and disadvantages of FEM and DEM models and the applications of FEM and DEM models to analyzing the stability of forested slope were compared in detail. Finally, the shortages of the current research on root reinforcement models were discussed and the direction of future development of root reinforcement models was predicted.
