Localized plant species-specific BVOC emission rate library

Localized plant species-specific BVOC emission rate library was established based on our and reported local field measurements, a statistical approach of classifying more detailed emission categories and assigning the representative emission rates used in BVOC emission inventory was developed. The developed library included the isoprene, monoterpene, and sesquiterpene emission rates for 599 native plant species. Critically, different level of reliability was given to each emission rate according to the measurement technique. This library will be significant for improving the accuracy of local biogenic emission inventory and furtherly the modeling of air quality.本研究基于团队自有及已发表的本地实地观测数据，构建了本地化的物种特异性生物挥发性有机化合物（BVOC）排放速率数据库；同时开发了一套统计方法，用于对更精细的排放类别进行分类，并为BVOC排放清单分配典型排放速率。所构建的数据库涵盖了599种本土植物的异戊二烯、单萜及倍半萜排放速率。尤为关键的是，本数据库依据观测所采用的测试技术，为每一项排放速率赋予了不同等级的可靠性评级。该数据库对于提升本地生物源排放清单的精度，乃至后续空气质量模拟的准确性均具有重要意义。
