Regional-scale mobile observations of atmospheric isoprene were conducted along a 2000km east-west transect in China's subtropical forest region using a mobile laboratory equipped with a high-resolution proton transfer reaction time-of-flight mass spectrometer (PTR-TOF-MS). The objective of this study was to elucidate the spatial distribution patterns of isoprene in this area. The results revealed significant spatial heterogeneity in isoprene concentrations, with an average value of (0.635 ± 0.204) μg/m3. The isoprene concentration in the Jiangnan forests, characterized by widespread bamboo and predominantly subtropical evergreen broadleaf species, was (0.629 ± 0.116) μg/m3, which was approximately 32.8% higher than the (0.474 ± 0.155) μg/m3observed in the Guizhou forests, primarily composed of conifers. These findings indicate that the spatial distribution and emission intensity of isoprene in forested areas are significantly influenced by vegetation composition. Moreover, in the industrially dense Zhejiang region, the isoprene concentration reached (0.881 ± 0.155) μg/m3, representing increases of 86.2% and 40.1% compared to the Guizhou and Jiangnan forests, respectively. These results suggest that in addition to the rich diversity of plant species, anthropogenic factors such as industrial and traffic activities also likely contribute to the elevated isoprene concentrations observed in this region.

通过搭载高分辨率质子转移反应飞行时间质谱仪(PTR-TOF-MS)的移动实验室,对中国亚热带森林区由东西向横断面(2000km)开展了区域尺度大气异戊二烯的移动观测,旨在揭示该区域大气异戊二烯的空间分布格局.结果表明,异戊二烯浓度存在显著的空间异质性,平均浓度为(0.635 ± 0.204)μg/m3.其中,江南森林以广泛分布的竹子和主要的亚热带常绿阔叶树种为特征,异戊二烯浓度为(0.629 ± 0.116)μg/m3,约比贵州森林中(主要为针叶林)的(0.474 ± 0.155)μg/m3高出32.8%,这表明植被组成显著影响森林异戊二烯空间分布和排放强度.而在工业生产活动密集的浙江区域,异戊二烯浓度达到了(0.881 ± 0.155)μg/m3,分别比贵州和江南森林分别高出86.2%和40.1%.除了该区域丰富的植被种类植物物种多样性外,工业活动、交通等人为因素也可能对该地区异戊二烯浓度偏高产生一定影响.

通过搭载高分辨率质子转移反应飞行时间质谱仪(PTR-TOF-MS)的移动实验室,对中国亚热带森林区由东西向横断面(2000km)开展了区域尺度大气异戊二烯的移动观测,旨在揭示该区域大气异戊二烯的空间分布格局.结果表明,异戊二烯浓度存在显著的空间异质性,平均浓度为(0.635 ± 0.204)μg/m3.其中,江南森林以广泛分布的竹子和主要的亚热带常绿阔叶树种为特征,异戊二烯浓度为(0.629 ± 0.116)μg/m3,约比贵州森林中(主要为针叶林)的(0.474 ± 0.155)μg/m3高出32.8%,这表明植被组成显著影响森林异戊二烯空间分布和排放强度.而在工业生产活动密集的浙江区域,异戊二烯浓度达到了(0.881 ± 0.155)μg/m3,分别比贵州和江南森林分别高出86.2%和40.1%.除了该区域丰富的植被种类植物物种多样性外,工业活动、交通等人为因素也可能对该地区异戊二烯浓度偏高产生一定影响.

Regional-scale mobile observations of atmospheric isoprene were conducted along a 2000km east-west transect in China's subtropical forest region using a mobile laboratory equipped with a high-resolution proton transfer reaction time-of-flight mass spectrometer (PTR-TOF-MS). The objective of this study was to elucidate the spatial distribution patterns of isoprene in this area. The results revealed significant spatial heterogeneity in isoprene concentrations, with an average value of (0.635 ± 0.204) μg/m3. The isoprene concentration in the Jiangnan forests, characterized by widespread bamboo and predominantly subtropical evergreen broadleaf species, was (0.629 ± 0.116) μg/m3, which was approximately 32.8% higher than the (0.474 ± 0.155) μg/m3observed in the Guizhou forests, primarily composed of conifers. These findings indicate that the spatial distribution and emission intensity of isoprene in forested areas are significantly influenced by vegetation composition. Moreover, in the industrially dense Zhejiang region, the isoprene concentration reached (0.881 ± 0.155) μg/m3, representing increases of 86.2% and 40.1% compared to the Guizhou and Jiangnan forests, respectively. These results suggest that in addition to the rich diversity of plant species, anthropogenic factors such as industrial and traffic activities also likely contribute to the elevated isoprene concentrations observed in this region.
