乐山景区负氧离子浓度分布及其等级划分研究
|
摘要
为研究乐山景区空气负氧离子浓度分布及等级划分,收集乐山4个景区负氧离子自动监测站数据,利用空气质量评价指数对其进行等级划分。研究表明:负氧离子浓度越大,CI值越大,空气质量等级越高,空气越清新;大气负氧离子浓度的空间分布特征呈现从东往西、从南往北逐渐增加的趋势;负氧离子浓度季节变化特征呈现:夏季>秋季>春季>冬季;同时海拔高度对负氧离子浓度有一定影响,同一景区,海拔较高的峨眉山高山区大气负氧离子浓度大于海拔较低的中山区。
In order to analyze the distribution and the grading of air negative oxygen ions concentration in Leshan scenic area,the data of negative oxygen ion automatic station built by Leshan in four tourist attractions in the city were collected,and the air negative oxygen ions concentration in Leshan was graded by probability simulation. The study showed that the concentration of the air negative oxygen ions is higher,the CI value is grater,the air quality grade is higher and air is fresher; The spatial distribution of the atmospheric negative oxygen ions concentration is showing the level increases gradually from east to west,from south to north. The concentration of negative oxygen ions showed obvious seasonal variation,which is characterized by summer > autumn > spring > winter. The altitude has a certain influence on the concentration of air negative oxygen ions,and in the same tourist attraction,The atmospheric negative oxygen ions concentration in the high mountain area of Mount Emei is higher than the lower mountains area of Mount Emei.
