英文摘要 | 2010年11月采集了黄河口潮滩湿地两种典型生态系统[碱蓬(Suaeda salsa)盐沼和光滩]表层土壤样品,进行了7d的室内厌氧培养,并测定分析CH4产生潜力及其对有机物和氮输入的响应。研究结果表明,在培养周期内,碱蓬盐沼和光滩表层土壤CH4的产生潜力都在培养的第7天后达到最大,平均值分别为0.0357μg/(g·d)和0.0013μg/(g·d),前者表层土壤的CH4产生潜力高于后者;有机物输入在一定程度上促进了CH4产生潜力,且其对碱蓬盐沼的CH4产生潜力较光滩具有更大的促进作用。尽管葡萄糖对于潮滩湿地CH4产生潜力的促进程度高于乙酸钠,但二者的差异性并不显著(p>0.05);氮输入对... |
中文摘要 | Topsoil (0-10 cm depth) from two typical ecosystems (Suaeda salsa salt marsh (SW) and mudflat (MF)) of the Yellow River estuary were collected in November 2010, and methane production potential of soil and its response to organic matter and nitrogen import were studied with anaerobic incubation. The results indicated that both methane production potential of soils from SW and MF occurred the maximum values after 7 days incubation during the experimental period, and the average were 0.035 7 μg/(g·d) and 0.001 3 μg/(g·d),respectively. The import of organic matter, to some extent, promoted the methane production potential of tidal marsh soil, and which has more effect on SW than that on MF. Although glucose had greater enhancement than that of sodium acetate, no significant difference was found between them (p>0.05). The effects of nitrogen import on methane production potential were related to nitrogen forms, and soil physical or chemical properties.The addition of ammonium (NH4+) had greater enhancement on methane production potential in SW compared to that in MF, but they had no significant difference (p>0.05). Nitrate (NO3-) addition inhibited the methane production potential in SW, while the promotion effect was observed in MF. Currently, because exogenous organic matter and nitrogen (NH4+—N is dominated) are major pollutants in the Yellow River estuary,the methane emission function of tidal wetlands should be paid more attentions when we estimate the GHGS inventory of the inter-tidal zone. |
