摘要
N2O是一种重要的温室效应气体,不仅具有很强的温室效应,而且参与大气对流层和平流层的许多光化学反应,因而在全球变化研究中受到广泛关注。本文对大气N2O的排放源的最新研究进展进行了综述。大气N2O的排放源包括自然源和人为源。自然源包括海洋、森林、草地等,人为源包括生物质燃烧及工业排放。土壤N2O排放约占全球N2O排放60%左右,因此,土壤是重要的N2O排放源。
N2O is a greenhouse gas much more radiactively active than CO2 and CH4(mass basis) at absorbing infrared radiation.It contributes greatly to global warming and to stratospheric O3depletion.There more and more attention was paid to N2O.Sources of atmospheric N2O include natural and anthropogenic sources.Natural sources include ocean,forests,grasslands and so on.Anthropogenic sources include biomass burning and industrial sources.Emission of N2O by soils account for about 60% of the global nitrous oxide.Therefore,soils are thought as to be major resource for nitrous oxide.
