湖北省旅游景区大气负氧离子浓度分布特征以及气象条件的影响

通过利用湖北省气象服务中心在全省27个旅游景区内建设的30个大气负氧离子自动监测站数据,对湖北省旅游景区大气负氧离子浓度分布特征及气象条件对负氧离子浓度的影响进行了分析。研究表明:湖北省旅游景区的大气负氧离子资源十分丰富,西部山区高于东部平原地区,整体呈现从东向西、从北向南逐渐增加的趋势,鄂西南地区为全省大气负氧离子最为丰富的地区,负氧离子浓度夏季最高,冬季最低,秋季略大于春季。从3月开始,负氧离子浓度逐月增加,至8月达到最大值,后又逐渐减小。凌晨和上午的负氧离子浓度要大于下午和晚上,夜间呈逐渐上升的趋势。大气负氧离子浓度晴天最大,阴天小于晴天,而雾霾天和小雨天负氧离子浓度均较小;中雨以上降水、闪电活动与负氧离子浓度呈正相关。

DISTRIBUTION CHARACTERISTICS OF AIR NEGATIVE OXYGEN ION CONCENTRATION AND THE INFLUENCE OF METEOROLOGICAL CONDITIONS IN TOURIST ATTRACTIONS IN HUBEI PROVINCE

This paper takes advantage of data from 30 air negative oxygen ions automatic stations in the 27 tourist attractions in Hubei Province constructed by Hubei Meteorological Service Center.We analyzed atmospheric negative oxygen ion concentration distribution characteristics and the influence of meteorological conditions to air negative oxygen ions.The study showed that the air negative oxygen is very rich in the tourist attractions of Hubei Province,being higher in the western mountainous area than in eastern plain area.The level increases gradually from east to west,from north to South,and the Southwest Hubei is area with most abundant negative oxygen ions.The concentration of negative oxygen ions is highest in summer,lowest in winter and slightly larger in autumn than in spring.From the beginning of March,the concentration of negative oxygen ions increased month by month,reached the maximum in August,and then decreased gradually.The concentration of negative oxygen ions in the morning is higher in the afternoon and evening,and gradually increased in the midnight.The air negative oxygen ion concentration is highest in sunny day,and lower in cloudy day rain days and haze days have lower negative oxygen ions.The moderate rainfall and lightning activity was positively correlated with the concentration of negative oxygen ions.
