Based on the survey on wind disasters in Hubei Province from 1965 to 2005, through analyzing some indexes, such as the frequency of wind disaster in each area and the loss of people and property, impact assessments on wind disaster for various areas are made. By means of the indexes as damagesuffering population and disasteraffected area, the grades of wind disaster are given, and in combination with the wind disaster frequency, the influence degrees of wind disasters are determined. According to the characteristics of disasterinducing factors and the analysis of vulnerability of hazardbearing bodies, using the hazard assessment model, an analytical chart of winddisaster risk degree is presented. It is shown that the Three Gorges valley and the eastern Jianghan Plain are the highestrisk areas of wind disaster.
