| 中文摘要 |
| 根据近期国内外相关文献,从植物VOC排放清单的角度,对不同空间尺度下植物VOC排放模型的建立与排放清单量值的估算进行了归纳,其中,中国植被VOC年排放总量的估算值(以C计)在12.4~28.4 Tg·a-1之间,2000年北京市园林绿地植物VOC年总排放量约为3.85万t. 另外,以北京城市为例,为确定城市大气污染物的总体减排对策,还进一步对园林植物VOC排放清单量值对大气中O3与SOA形成的贡献进行了介绍,在同一时期内,相比园林植物,人为源排放的活性芳香烃类化合物和烯烃类对大气中O3的产生贡献最大,人为源排放的芳香烃还是北京SOA生成潜势的主要贡献源. 最后建议重点控制城市人为源的VOC排放,这将对降低北京城市臭氧与二次有机气溶胶污染起到关键作用. |
| 英文摘要 |
| Reference to relative literatures in recent years, model building and calculation on volatile organic compound(VOC) emission inventory of plants were summarized in different spatial scales, the total annual VOC emission amounts from Vegetation in China are in the range from 12.4 Tg·a-1 to 28.4 Tg·a-1. For garden plants in Beijing, the annual VOC emissions are approximately 38500 tons C in 2000. Furthermore, in order to determine reduction strategies for Beijing urban atmospheric major pollutants, the contribution of garden plant VOC emissions to the ozone and secondary organic aerosol(SOA) formation was presented, compared to garden plant in the same period, the largest contribution to ozone formation comes from aromatic hydrocarbons and olefin which are exhausted from anthropogenic activity, besides, the aromatic hydrocarbons exhausted from anthropogenic activity is also a main contribution source for the potential formation of SOA. In the meantime, it is suggested to focus on emission control of VOCs which are emitted from urban anthropogenic sources. |
