Abstract:Based on the air quality indicators, daily level of air quality, air pollution index, to analyze the changes in the characteristics of air quality of Kunming City in recent 8 years, and to use fuzzy comprehensive evaluation model to make a comprehensive evaluation of air quality. The results show that: Over the past 8 years, SO2 , NO2 , PM10 of Kunming City take on clear downward trend, air quality compliance rate is more than 95% ,during the year air quality is the best during the rainy season when the monthly average value of API is 59, while API is 67 in the dry reason, so the air quality is relatively low, ambient air quality is under 2, the level of air pollution has heen significantly improved.
Keywords:the urban area of Kunming  air of environment  air quality  the changes in the characteristics  air pollution index  comprehensive fuzzy  evaluation model
