Our group assumes that the report number of the air pollution from the media has become more and more; it rises up our curiosity for the information about air pollution. Our group collects the report number of the air pollution from Medias, and then we found that it actually becomes more and more, from statistics and analysis aspects. We also found partially citizen feel the air pollution become worse than before. We focus on this part and analyze the cause; maybe it is because of the changing of the way of evaluation on the air quality standard (pm2.5 -->AQI), it becomes stricter and makes the citizens more sensitive. Thus, we will do the questionnaire to realize whether the reports are right or wrong. We focus on the questionnaire about the citizens in Xitun and Longjing Dist., Taichung City by asking their feelings (results and analysis). After analyzing the questionnaire, the data shows that the citizens actually don’t feel the air pollution becomes worse than before but feel the air quality becoming better. (Analysis: Due to the amount of the report of the air pollution becoming more and more, the citizens pay more attention to the air quality. Further infects their frequency of following these kinds of information actively and obviously changing their lifestyle. However, we found that the rate of right answer for the standard of air pollution filled by people live more and less than five years in Xitun and Longjing Dist., Taichung City are almost the same. Therefore, we believe that the increasing amount of news about air pollution didn’t improve their right cognition about the real conditions of air pollution.
