Biogenic volatile organic compound emissions in relation to plant carbon fixation in a subtropical urban-rural complex

- Bamboo forest is the major contributor to the BVOC emissions also an important loss of carbon in low-latitude subtropical Ningbo.
- Contribution of carbon emitted as BVOC to NPP (BVOC/NPP ratio) for built-up areas is higher than rural forests (excluding bamboo forest).
- BVOC/NPP ratios between native and exotic tree species exhibit no significant difference.
- G. biloba, L. chinensis and S. mukorossi are the top three tree species with beneficial BVOC/NPP ratios in subtropical urban area.
- BVOC/NPP ratios increase with a drop in latitude.
