  • 摘要:利用数值模拟方法结合GEIA生态源排放清单, 研究了夏季我国东部生态系统排放非甲烷烃(NMHC)对臭氧和过氧乙酰硝酸脂(PAN)的影响, 阐明了生态NMHC在大气化学系统中的重要作用.研究结果表明, 生态NMHC使我国东部大部分地区臭氧和PAN增加, 最大平均增量分别为9ppb和0.6ppb;白天最大平均增量分别达到2.1ppb和1.2ppb, 最大增量地区位于长江三角洲的浙江、上海附近地区.模拟结果与实测值有好的一致性, 研究结果表明对于区域和城市臭氧的模拟及其控制应该充分考虑生态源的作用.
  • Abstract:By numerical simulation method and GEIA biogenic emission inventory, the effect of biogenic non methane hydrocarbon (NMHC) on ozone and PAN in east China in summer were investigated and the importance of biogenic NMHC to atmospheric chemistry system was illustrated. The results showed that ozone and PAN in most area of east China were increased by biogenic NMHC, the average maximum increment of ozone and PAN were 9ppb and 0 6ppb respectively. The average maximum increment in daytime even reached to 21ppb and 1.2ppb respectively, which appeared in Shanghai and Zhejiang Province. Model results showed good agreement with observation and also indicated that biogenic NMHC should be adequately considered in simulation and control of regional and urban ozone.
