The method of "empirical data assimilation for the SARS epidemic trend model" is used to assimilate the model parameters based on the new crown epidemic data released by the Health Committee of each city, and our research team's recent work is presented, including the multiple epidemic trend analysis and the decision-making suggestions for the whole country (except Hubei), Hubei Province (except Wuhan) and Wuhan city from February 3 to February 28, 2020. Three prediction curves are shown as the guideline of the epidemic prevention and control to predict the development of the epidemic. The epidemic peak line of the model can be used as a standard line to evaluate whether the current epidemic prevention measures are appropriate and be used for the early warning of the epidemic trend in various cities, to guide the proper taking of the epidemic prevention measures, to provide the decision support for the scheduling of medical resources and emergency supplies for life, and to play a role in stabilizing the public mood.
