摘　　要：Natural peatlands are a source of CH_(4) emission but a sink of CO_(2) and N_(2)O.On the other hand,peatlands drained for agricultural use suppress CH_(4) emission but become a source of CO_(2) and N_(2)O emissions.Drained peatland area accounts for 2% of the world's agricultural land,but its greenhouse gas(GHG)emissions account for 7%of global GHG emissions.Immediately after land clearing,N_(2)O emission significantly increases due to nitrogen(N)fertilization.
