摘　　要：氮氧化物(NOx)是全球氮循环的重要形式,也是影响全球气候和环境的重要污染气体。近年来随着人为源NOx排放量的逐渐下降,自然源NOx的释放通量及机制越来越受到人们的关注。本文综述了NOx的来源、气候和环境效应、释放通量估算方法和典型生态系统中自然源NOx释放通量特征及影响因素。然而,目前对不同生态系统NOx的研究还不够系统和深入,建立NOx标准测定方法和通量估算方法,对不同生态系统特别是海洋及湿地NOx的源汇格局,微生物的作用机制、人为氮输入的影响等开展系统地研究,才能准确评价不同生态系统对大气NOx的贡献及变化趋势,完善全球氮的收支平衡研究。Nitrogen oxides(NOx)are important compounds in global nitrogen cycle,whichare also important pollutants that affect global climate and environments.In recent years,with the gradual decline of man-made NOx emission,more and more attention has been paid to the emission fluxes and releasing mechanisms of natural NOx.The sources of NOx,the effects on climate and environments,the emission flux calculation methods and the NOx emission fluxes from natural sources in typical ecosystems are summarized.Nevertheless,at present,the research on NOx in different ecosystems is not systematic and in-depth.Only by establishing NOx standard measurement methods and flux estimation methods,conducting systematic research on the source and sink patterns of NOx in different ecosystems,especially in the ocean and the wetland,the function mechanisms of microorganisms,and the impact of anthropogenic nitrogen input,we can accurately evaluate the contribution of different ecosystems to atmospheric NOx and their change trends and improve the research on global nitrogen budget balance.
