英文摘要	[ 1] Methane (CH(4)) fluxes were measured in hypereutrophic Meiliang Bay of Taihu Lake with static chambers for 1 year. The results showed that the macrophyte-covered infralittoral zones were the "hotspots'' of CH(4) emission in water systems. There were large temporal variations for CH(4) fluxes, ranging from - 1.7 to 131 mg CH(4) m(-2) h(-1), in the macrophyte-covered littoral zone. The highest CH(4) emissions occurred during the period of the summer algal bloom. The amount of CH(4) flux from June to September accounted for about 50 -90% of the annual fluxes. CH(4) fluxes from the bare infralittoral zone ( - 0.2 similar to 4.2 mg CH(4) m(-2) h(-1)) were low and close to those in the pelagic zone. The difference in CH(4) fluxes between macrophyte-covered and bare infralittoral zones indicated that vegetation in the inundated area played an essential role in CH4 production. In the infralittoral zone, the redox condition (DO, Eh), temperature, and primary production controlled CH(4) fluxes; these variables explained 47% of flux variation, whereas such influences were not detected in the pelagic zone.
