It is a dynamic explanation model that simulates the annual crop growth with the specifi c soil and climatic conditions. The model emphasizes the application of land quantitative evaluation, regional yield forecast, risk analysis, the annual yield changes and quantization of the effects of climate change. The simulation of model is based on the crop physiological and ecological process, including assimilation, respiration, transpiration and dry matter distribution. WOFOST model consists of three levels of the crop growth simulation, the potential growth conditions, water-limited and nutrient-limited conditions. This paper introduces the development and application of WOFOST model, its theoretical basis and operation and so on, to facilitate more people to quickly understand, grasp and use the model, and further promote the development of crop models in our cou
