2012年7月至2013年1月,在我国浙江省亚热带竹林开展了挥发性有机物(BVOCs)排放、O3、太阳辐射、气象参数等的综合测量。基于PAR能量平衡原理和冠层尺度异戊二烯和单萜烯排放经验模式,建立了考虑O3与异戊二烯和O3与单萜烯关系的O3经验模式,该模式对于O3日变化和平均值有较好的模拟。对经验模式进行了检验,结果表明它可以较好地捕捉O3的变化特征。利用经验模式计算了O3对各个因子(异戊二烯或单萜烯、PAR、水汽、S/Q-散射因子,散射辐射/总辐射)变化的敏感性:对于O3与异戊二烯关系的O3经验模式,O3对PAR的变化最敏感,其次是水汽因子,再次是异戊二烯;最后是S/Q;对于O3与单萜烯关系的O3经验模式,O3对PAR的变化最敏感,其次是水汽和S/Q因子,最后是单萜烯;O3对各因子变化的响应均是非线性的。敏感性研究给出了与实测数据较为一致的结果,增加了我们对于O3、BVOCs化学和光化学机制的理解和认识。基于测量和敏感性研究,提出未来控制高浓度O3污染的一些建议:控制人为原因引起的BVOCs排放、人为源挥发性有机物排放、以及NOx和SO2排放等。 During July 2012-January 2013, integrated measurements of biogenic volatile organic compounds (BVOCs), O3 and solar radiation at a subtropical bamboo forest, Zhejiang province, were carried out. Based on PAR energy balance and empirical models of isoprene and monoterpene emissions at canopy scale, O3 empirical models considering the relationships between O3 and isoprene and O3 and monoterpenes, respectively, were developed. O3 diurnal variation and mean value were better simulated by O3 empirical models. The validation of O3 empirical models was made, which showed that it can capture O3 variation characteristics. A sensitivity study of the response of O3 to changes in its controlling factors (i.e., isoprene or monoterpenes, PAR, water vapor and S/Q-scat- tering factor, ratio of solar scattering radiation to solar global radiation) showed that O3 was most sensitive to PAR, and more sensitive to water vapor, isoprene emission and S/Q, for O3 empirical model considering the relationship of O3 with isoprene emission; O3 was also most sensitive to PAR, and more sensitive to water vapor, S/Q and monoterpene emissions, for O3 empirical model considering the relationship of O3 with monoterpene emissions. The responses of O3 to changes of all controlling factors were nonlinear. The sensitivity studies exhibited good agreements with the observations, and improved our understanding of chemical and photochemical mechanisms associated with O3 and BVOCs. Some suggestions in controlling future high O3 pollution were put forwarded, e.g., controlling emissions of Human-induced BVOC emissions, anthropogenic volatile organic compound emissions, and NOx and SO2 emissions.
