Abstract: Crop growth model is a useful tool for quantitative evaluation of crop production potentials. Since itsstudy was first published in 1985, EPIC model has been widely used in the world because of its powerful functionality.In this paper, the main structure, function and data requirements were firstly summarized, and then the model applications in the world and China were reviewed. In China, since the first application in 2001, the EPIC model was used to evaluate crop yield potentials, quantify effects of irrigation and climate change on crop production,estimate nutrient losses and soil carbon storage, and predict soil losses. Finally, a brief discussion and suggestions were given on the model use.

Key words: EPIC model, model application, parameter
