摘要:
Measurements of net methane flux were made during the 1988 ice-free season (May-October) at a beaver-meadow complex in northern Minnesota, USA. The site included upland boreal forest, sedge meadow, submerged aquatic plants, and the open water of a beaver pond. Annual fluxes were 8-11 g C/m<sup>2</sup> in the permanently wetted zones and 0.2-0.4 g C/m<sup>2</sup> at the occasionally inundated meadow and forest sites. These data, when coupled with long-term (46 yr) data on beaver (Castor canadensis) population size and habitat alteration, suggest that about 1% of the recent rise in atmospheric methane may be attributable to pond creation by beaver in North America.
