The results show that annual emission of VOCs dis- charged by plants in Nanjing is about 0.004 9 Tg C. The annual emmisions of isoprene, monoterpene and other VOCs account for 18.0%, 25.9% and 56.1% of total emission of VOCs respectively. VOCs discharged by afforesting vegetation in Nanjing has the greatest impact on average con- centration of ozone in winter.展开更多
