Abstract:
Based on the micro-blog data of Xi′an tourists, and employs amendatory “MBEWC” to calculate the emotion value of tourists, the relationship between emotional tendency and air quality are studied. The results show that five pollutants including PM2.5, PM10, NO2, SO2 and CO have weak negative correlation with tourists′ micro-blog emotion index.Among all the pollutant indexes, NO2 has the largest impact on tourist emotion and the emotion value of tourists goes down 21 points when every 1 000 μg NO2 is discharged specifically.As for PM2.5 and PM10, PM10 has less influence than PM2.5 on tourist emotion because PM2.5 has smaller grain size which is harder to defend.For gaseous pollutants, NO2 and SO2 have much greater impact on tourist emotion than CO.It has been found that a variety of pollutants in the air bring larger effect on tourist emotion than sole one,such as,it has larger influence on tourist emotionwhen PM2.5 and SO2 exist at the same time than SO2 alone.
