Methane uptake in forest soils along an urban-to-rural gradient in Pearl River Delta, South China

We investigated soil CH(4) fluxes from six forests along an urban-to-rural gradient in Guangzhou City metropolitan area, South China. The most significant CH(4) consumption was found in the rural site, followed by suburban, and then urban forest sites. The rates of CH(4) uptake were significantly hi...

description We investigated soil CH(4) fluxes from six forests along an urban-to-rural gradient in Guangzhou City metropolitan area, South China. The most significant CH(4) consumption was found in the rural site, followed by suburban, and then urban forest sites. The rates of CH(4) uptake were significantly higher (by 38% and 44%, respectively for mixed forest and broadleaf forest) in the rural than in the urban forest site. The results indicate that soil water filled pore space (WFPS) is the primary factor for controlling CH(4) consumption in subtropical forests. The reductions of soil CH(4) uptake in urban forests were also influenced by the higher rates of atmospheric nitrogen (N) deposition and increases in soil nitrate (NO(3)(−)) and aluminum (Al(3+)) contents as a result of urbanization. Results from this work suggest that environmental changes associated with urbanization could decrease soil CH(4) consumption in subtropical forests and potentially contribute to increase of atmospheric CH(4) concentration.
