| Abstract: | A relatively systematic experiment on the relationship between ozone generation and VOCs was carried out from Nov 20th, 2013 to Jan 20th, 2014. Based on the observed data of the experiment, Alkenes made a major contribution to the LioH and aromatic hydrocarbon dominated OFP in Xinghai district of DaLian city. According to the OH loss rate coefficient （LioH ） and the ozone formation potential （OFP）, key reactivie species of VOCs for the ozone formation in Xinghai District of DaLian city were recognized. They were propylene, toluene, m, p - xylene. |
