| 中文摘要 | 2010年11月,采集了黄河口北部滨岸高潮滩、中潮滩、低潮滩和光滩表层土壤样品,基于短期培养实验,研究了不同潮滩土壤CH_4氧化潜力及其对有机物输入的响应。结果表明,尽管4种湿地土壤的CH_4氧化潜力存在一定差异(P>0.05),但整体变化规律相似。12~60 h,CH_4氧化潜力均呈先增加后降低变化;60~132 h,CH_4氧化潜力均呈迅速增加趋势。4种湿地土壤CH_4氧化潜力整体表现为光滩(2.37 μg/g·d)>低潮滩(2.29 μg/g·d)>中潮滩(1.70 μg/g·d)>高潮滩(1.47 μg/g·d)。甲醇输入整体抑制了湿地土壤的CH_4氧化潜力,抑制程度表现为光滩>中潮滩>低潮滩>高潮滩。4种湿地土壤的CH_4氧化潜力分别为1.27,0.49,0.67和0.38 μg/(g·d),较对照组降低13.56%,70.98%,70.65%和83.83%;酵母膏输入对高潮滩、中潮滩和光滩土壤的CH_4氧化潜力表现为促进作用,促进程度表现为中潮滩>高潮滩>光滩。3种湿地土壤的CH_4氧化潜力分别为2.89,2.41和2.96 μg/(g·d),较对照组增加69.38%,64.01%和24.76%。与之相比,酵母膏对低潮滩土壤的CH_4氧化潜力表现为弱抑制作用,其氧化潜力为2.14 μg/(g·d),较对照组降低6.67%。可见,不同有机物对潮滩湿地土壤CH_4氧化潜力的影响差异较大,在当前外源有机物为黄河入海主要污染物情况下,潮滩湿地CH_4的源/汇功能将会发生明显变化,这就使得在估算黄河口潮滩CH_4排放清单时应特别关注不同有机物输入对CH_4释放的影响。 |
| 英文摘要 | Topsoil samples in four typical ecosystems [high tidal marsh (HM), middle tidal marsh (MM), low tidal marsh (LM) and the bare flat (BF)] of the Yellow river estuary were collected in November 2010. The methane oxidation potential and its response to organic matter import were studied after incubating in an aerobic environment for six days. The methane oxidation potential of different soils differed (P>0.05). Similar changes of oxidation potential of different soils were observed during the experimental period of 12-60 h when the oxidation potential initially increased but then decreased. The values then increased rapidly and reached a maximum at the end of the incubation period. The order of oxidation potential of different soils was BF>LM>MM>HM, and the average values were 2.37, 2.29, 1.70 and 1.47 mug/(g·d), respectively. The import of methanol inhibited the methane oxidation potential of marsh soils to some extent, in the order BF>MM>LM>HM. The average oxidation potentials of the different marsh soils were 1.27, 0.49, 0.67 and 0.38 mug/(g·d), which decreased 13.56%, 70.98%, 70.65% and 83.83% respectively, compared with the controls. Comparatively, the import of yeast extract promoted the methane oxidation potential of BF, MM and HM (values of 2.89, 2.41 and 2.96 mug/g·d, respectively), which increased 69.38%, 64.01% and 24.76% compared with the controls. The import of yeast extract inhibited the methane oxidation potential of LM, and the value was 2.14 mug/(g·d) which decreased 6.67% compared with the controls. When estimating the list of greenhouse gases emissions in the intertidal zone, more attention should be paid to the CH_4 sink/source functions of tidal marsh as exogenous organic matters are the main pollutant for this area. |
