英文摘要	Based on VaR model in finance mathematics, EVR model of ecological risk management is established and it is applied in the air pollution in Laoshan District of Qingdao. According to the data of daily air quality index from 2001 to 2005, the fitting probability distribution of air quality index in spring, summer, autumn and winter has been calculated. Each probability distribution has passed Anderson-Darling, Chi-square and Kolmogorov-Smirnov test under 5% significance level. The case study of EVR ecological risk of air pollution in Laoshan District of Qingdao showed the EVRs are different in different confident levels and risk benchmarks. It is found that the variation of air quality index in spring is more obvious than that in winter, and then the following sequence is the summer and the autumn.. In 60% confidence level, the air quality of in the whole year is in good state. The relative the ecological risk EVR(R) of air quality in Laoshan District is used to describe the fluctuation of air quality index, while the absolute ecological risk EVR(A) of air quality in Laoshan District taking the air pollution index of '100' as the benchmark is to represent the deviation of worst air quality differing from it in a given confidence level. It is found that with the rise of confidence level, the probability of occurrence of air pollution except for in summer is gradually increasing.
