Abstract: The objective is to improve the greenhouse environment model and achieve the optimal control of the production process. Based on the over ground environment in greenhouse, the environmental factors and the static and dynamic models are used as the standards of division, the research progress and existing problems in the single-factor environmental models, multi-factor integrated models, the static and dynamic models are analyzed and summarized. Furthermore, the simplified methods of greenhouse models are concluded. Lack of accurate models is the main issue regards to greenhouse environment control. Finally, on the basis of the balance of energy, quality and material and in consideration of crop quality, yield and economic cost, it is proposed that the establishment of the accurate greenhouse environment model with modern optimal control theory is the future research direction.
