| 摘 要： | 测定了厦门东屿白骨壤（Avicennia
marina）林土壤的甲烷产生量及其在土壤中的氧化、传输与库量．土壤甲烷产生量基本上呈内滩>中滩>外滩的滩面变化趋势，季节变化趋势为秋、冬季低于春、夏季，与甲烷氧化量的时空变化模式一致，与甲烷库量的时空变化模式也基本相同．所有季节所有滩面土壤甲烷产生量、氧化量、库量的平均值分别为9.11mg/(m |

Methane production, oxidation, transportation rate and pool |
|
| Abstract: | Methane production, oxidation, transportation rate and pool were determined in sediments of an Avicennia marina mangrove at Dongyu, Xiamen. The flat pattern of methane production was inner-flat>mid-flat>out-flat and the values in winter and autumn were lower than that in summer and spring. The spatial and temporal patterns of methane oxidation and pool were similar to those of methane production. The values of methane production, oxidation and pool averaged from all flats and seasons were 9.11, 7.58 mg/(m2*d) and 27.07 mg/m2, respectively. The ratios of methane oxic oxidation to total oxidation in inner-flat, mid-flat and out-flat were 99.7%, 59.1% and 75.4%, respectively, higher than those of anoxic methane oxidation. Methane transportation rate was highest in summer and lowest in winter and the value averaged in all flats and seasons was 17.06%. |
