| 英文摘要 | Until the end of last century, scientists began to show their concern about greenhouse gas emission from reservoirs and questioned the ‘‘green credential’’ of hydroelectric dams since then. Through measurements along the channel of the TGR, an unexpectedly low CH4 emission rate was recently observed from the surface of the TGR, much lower than our assumed estimate before. Moreover, the rate from the TGR is lower than that from many hydroelectric reservoirs. One possible reason for such a low emission rate is that lack of substrates supplied by decomposed vegetation limits the CH4 production in the sediment of the TGR because of vegetation clearance since 2002 before impounding, whose primary purpose is to conserve the water quality. These results indicated that TGR is not a hotspot of CH4 emission. On a broader sense, it also indicated that removal of flooded vegetation would help to decrease CH4 emission from dam reservoirs before impounding, especially in the drawdown area. |
