| 摘 要： | 采用室内厌氧培养法研究闽江河口潮汐盐湿地甲烷产生不同底物(醋酸、甲醇和三甲胺)及电子受体(SO42-、NO3-和NH4+)对外来入侵种互花米草Spartinaalterniflora湿地表层沉积物甲烷产生潜力的影响,结果表明:盐湿地非竞争性甲烷产生底物中的甲醇对互花米草湿地表层沉积物甲烷产生潜力的促进作用最大,高于醋酸和三甲胺,且3种底物的添加均在培养5d后对沉积物甲烷产生潜力的促进作用最为明显;随着培养时间的增加,不同浓度的SO42-、NO3-、NH4+的添加对沉积物甲烷产生潜力的影响呈现出抑制作用或无抑制作用2种结果,添加电子受体的浓度越高,对沉积物甲烷产生潜力的抑制作用越显著。

| Abstract: | Effects of methane production substrates （acetate, methanol and trimethylamine）i electron acceptors （SO4^2-,NO3^-and NH4^＋） on methane production potentials from alien invasive Spartina alterniflora wetland patch surface sediment in the Min River estuary wetland were determined by laboratory anaerobic incubation experiments. The results showed that, non-competitive methane production substrates-methanol （CH3OH） had the greatest enhancement on methane production potential, which was higher than that of trimethylamine and acetate; the addition of different concentrations of SO4^2- ,NO3^- and NH4^＋ can promote or inhibit methane production potential over the incubation period, and the most significant inhibiting effect was found of the highest concentration on methane production potential. |
