英文摘要The littoral zones of lakes have been regarded as hotspots of methane (CH4) fluxes through several studies. In the present study, we measured CH4 fluxes in six kinds of littoral zones of Huahu Lake on the Qinghai-Tibetan Plateau in the peak growing season of 2006 and 2007. We found that CH4 efflux (ranging from -0.1 to 90 mg CH4 m(-2) h(-1)) from the littoral zones of this lake was relatively high among those of boreal and temperate lakes. Our results also showed that emergent plant zones (Hippuris vulgarls and Glyceria maxima stands) recorded the highest CH4 flux rate. The CH4 flux in the floating mat zone of Carex muliensis was significantly lower than those of the emergent plant zones. CH4 fluxes in the floating-leaved zone of Polygonum amphibium and bare lakeshore showed no significant difference and ranked last but one, only higher than that of the littoral meadow (Kobresia tibetica). Plant biomass and standing water depths were important factors to explain such spatial variations in CH4 fluxes. No significant temporal variations in CH4 fluxes were found due to the insignificant variations of physical factors in the peak growing season. These results may help in our understanding of the importance of the littoral zone of lakes, especially the emergent plant zone, as a hotspot of CH4 emission. (C) 2009 Elsevier Ltd.
