the major natural sources of atmospheric methane include enteric fermentation in ruminants and some insects, and the anaerobic decomposition of organic matter in waterlogged soils.
甲烷的主要自然源包括反刍动物和一些昆虫的肠发酵及淹水土壤的有机物的厌氧分解。
rather than releasing carbon dioxide, anaerobic decomposition releases methane or hydrogen sulfide, and the stream or lake turns dark and malodorous.
在这一过程中不是释放二氧化碳,厌气分解释放甲烷或者硫化氢,河流和湖泊就会变黑并发生恶臭。
these processes are controlled by anaerobic decomposition of soil organic matter and respiration and excretion of rice roots, relating to soil proper-ties as well.
其转化主要受土壤有机质嫌气分解和水稻根系呼吸及分泌作用的制约,并与土壤基本性质密切相关。
