摘要：
The aim of this study was to correlate magnitude andcontrols of CH4 fluxes with the microtopographyand the vegetation in a hollow-ridge complex of araised bog. High CH4 emission rates were measuredfrom hollows and mud-bottom hollows, while hummocksconsumed atmospheric CH4 at a low rate. Thehighest emissions were measured from plots with Eriophorum vaginatum and Scheuchzeriapalustris. CH4 emission ceased after Scheuchzeria had been clipped below the water table,indicating the importance of this aerenchymatic plantas a conduit for CH4.
