摘要

Methane (CH_4) is a very dangerous greenhouse gas, and its atmospheric concentration is rising due to natural and anthropogenic disturbances. Anthropogenic disturbances such as forest clearing, land-use changes and farming practices all result in considerable increases in N inputs and alterations in soil properties, including the CH_4 sink potential of the soil. Forest soils contribute to the consumption of CH_4 due to the presence of methano-trophic bacteria. It is proposed that the restoration of degraded forest ecosystems or unused degraded land may significantly contribute to the recovery of methanotrophic activity in the soil and thereby the soil CH_4 sink potential.
