| 中文摘要 | to assess the impact of livestock grazing on the emission of greenhouse gases from grazed wetlands, we examined biomass growth of plants, co2 and ch4 fluxes under grazing and non-grazing conditions on the qinghai-tibetan plateau wetland. after the grazing treatment for a period of about 3 months, net ecosystem co2 uptake and aboveground biomass were significantly smaller, but ecosystem ch4 emissions were remarkably greater, under grazing conditions than under non-grazing conditions. examination of the gas-transport system showed that the increased ch4 emissions resulted from mainly the increase of conductance in the gas-transport system of the grazed plants. the sum of global warming potential, which was estimated from the measured co2 and ch4 fluxes, was 5.6- to 11.3-fold higher under grazing conditions than under non-grazing conditions. the results suggest that livestock grazing may increase the global warming potential of the alpine wetlands.
