| 英文摘要 | To examine the effects of soil warming on carbon-accumulation and -release processes in the wetland ecosystem, a field-warming experiment was conducted under flooded and unflooded water conditions in the typical meadow calamagrostis angustifolia (c. angustifolia) (tmc) wetland in the sanjiang plain, northeast china. warming cables were used to simulate soil warming. warming caused significant increases in aboveground biomass compared with belowground biomass during the growing season, and the enhancement of aboveground biomass increased with plant growth while belowground biomass showed an opposite effect. significant positive correlation was found between aboveground biomass and 10-20-cm soil [image omitted] content whereas belowground biomass was more significantly correlated with 0-10-cm soil [image omitted] content. positive linear correlations were found between co2 and ch4 fluxes and warming-induced changes in liable carbon (lbc) and carbohydrate carbon (chc) contents. flooded water conditions tended to increase the accumulation of belowground biomass, [image omitted] content and ch4 fluxes under warming treatment. soil warming could not only stimulate the carbon-accumulation and -release processes in the tmc wetland ecosystem directly, but also indirectly through the enhancement of nitrogen availability and active carbon contents. the contents of [image omitted] and active carbon could be sensitive indicators for the carbon-process changes in wetland ecosystems under soil warming. |
