【摘要】 应用《1:1000000 中国植被图集》数据,按照 Guenther 等提出的最新算法,结合土地使用情况,对中国植被 VOC 的排放情况进行了比较全面和系统的研究.结果表明,全国植被 VOC 的年总排放量约为 17.1TgC,其中异戊二烯为 4.85TgC,单萜烯为 3.29TgC,其它 VOC(OVOC)为8.94TgC.植被 VOC 的排放量分布情况与中国植被的分布情况有一定的相关性,并且 VOC 的排放情况具有明显的季节依赖性.更多还原

【Abstract】 Applying 《1:1000000 vegetation atlas of China》 data, the relatively comprehensive and systematic study of vegetation VOC emission state in China was carried out according to the newest calculating technique suggested by Guenther et al, and combining with the land using state in China. The annual total emission amount of national vegetation VOC 4.85TgC for isoprene was about 17.1TgC, in which 3.29TgC for monoterpenes and 8.94TgC for other VOC(OVOC). The spatial distribution of vegetation VOC emission fluxes is corresponded with the distribution of the vegetation and vegetation VOC emission fluxes are also varying with the seasons.更多还原
