【摘要】：利用西安市國(guó)內(nèi)游客發(fā)布的微博數(shù)據(jù),采用修正的"微博情感傾向算法驗(yàn)證程序"(MBEWC)計(jì)算游客的情感傾向值,對(duì)情感傾向和空氣質(zhì)量進(jìn)行相關(guān)分析,研究情感傾向和空氣質(zhì)量的相互關(guān)系。研究發(fā)現(xiàn):PM_(2.5)、PM_(10)、NO_2、SO_2、CO這5種污染物均與游客微博情感值呈現(xiàn)較弱的負(fù)相關(guān);在所有污染物指標(biāo)中,NO_2對(duì)游客情感的影響程度最大,具體表現(xiàn)為每多排放1 000μg NO_2,游客微博情感值下降21分;其次,在煙塵污染物PM_(2.5)和PM_(10)中,PM_(2.5)粒徑很小,對(duì)游客情感的影響比PM_(10)嚴(yán)重;而對(duì)于氣體污染物,NO_2和SO_2對(duì)游客情感的影響程度遠(yuǎn)大于CO�？諝庵卸喾N污染物同時(shí)存在對(duì)游客情感的影響要明顯大于某一污染物單獨(dú)存在時(shí)的影響,具體表現(xiàn)為PM_(2.5)和SO_2同時(shí)存在對(duì)游客情感的影響程度大于SO_2單獨(dú)存在對(duì)游客情感值的影響。
[Abstract]:Using Weibo data released by domestic tourists in Xi'an, the modified Weibo algorithm Verification Program is used to calculate the emotional tendency of tourists. The relationship between affective disposition and air quality was analyzed and the relationship between affective tendency and air quality was studied. All of the five pollutants were negatively correlated with the emotional value of Weibo. Among all the pollutant indexes, no2 has the greatest influence on tourists' emotion, which is shown as follows: 1 000 渭 g / kg No2 is discharged, and the emotional value of Weibo decreases by 21 points. Secondly, in the case of the smoky pollutants PMCs 2.5 and 10), the particle size is very small, and the impact on tourists' emotions is more serious than that on PM10); And for gas pollutants. The influence of NO_2 and SO_2 on tourists' emotion is much greater than that of CO.There are many pollutants in the air at the same time and the influence on tourists' emotion is obviously greater than that when a pollutant exists alone. The influence of SO_2 and SO_2 on tourists' emotion is greater than that of SO_2 alone.
