摘要
在介绍有机挥发物与植物精气成分的基础上,微观层面对比分析了3种主流的植物活体状态下精气成分测定方法,阐述早期运用、晚期改进后的测定方法与其测得的精气成分结论。研究的宏观层面,介绍了城市区域乃至全国范围植物精气的现有主要估算模型,对比其研究的结论、关键因素和总结模型尚需完善部分。为完善和改进植物活体精气成分测定体系提供依据,提出应建立我国的以树种为单位的排放因子与全面的成体系的估算模型,从而为利用活体植物精气作用促进我国现有大气问题的解决提供依据。
On the basis of introduction of VOCs ＆ BVOCs, at the microscopic level, contrast and analyze three dominant composition determination methods of VOCs of living plant. Expound determination methods and conclu- sion of earlier stage and later stage. Macroscopic aspects, the existing major estimation models of BVOCs in urban areas and even nationwide are introduced. Compare study conclusion ＆ critical factors and summarize where needs be improved. The basis of the determination system of the living plant VOCs is provided. Emission factors based on tree species of China and systematic estimation models should be established. Consequently, provide the basis of using living plant VOCs to solve current atmospheric problems of China.
