Lifecycle carbon emissions (CE) of different tree species across urban green space types.

Relative contribution of different emissions factors to carbon emissions.

Life cycle carbon budget of major urban tree species across different green space types.
Error bars: mean ± SD, n = 3 sites × 10 trees/species.
Fig 4.
(a) represents the large tree species with the best carbon budget level in different green space environments and the green space environment group; (b) represents the small tree species with the best carbon budget level in different green space environments and green space environment grouping.
The “which-won-where” pattern in the GGE biplot identifies which genotypes perform best under specific environmental conditions, illustrating species × environment interactions across urban green space types.
Fig 5.
(a) and (b) respectively represent the comprehensive ranking of carbon budget of large trees and small trees in different green space environments.

Correlation analysis of plant carbon storage, carbon emissions and influencing factors.
Influencing factors refer to CS: soil compaction; SOC: soil organic carbon; Ia: Annual irrigation volume; Dp: density of planting; Ip: pruning intensity; Ta: air temperature; Ts: carbon storage; Te: carbon emissions. **P < 0.01; *P < 0.05.
