    摘要:

    土壤是N2O的重要排放来源之一。土壤中N2O产生途径众多、受多种因素调控,深入分析土壤N2O产生途径才能采取针对性的减排策略。稳定同位素技术已广泛用于研究土壤N2O排放,N2O同位素异位体法是近年来新兴的研究方法。该研究方法通过测定土壤N2O的同位素组成(δ15NSPN2Oδ18ON2Oδ15NbulkN2O)分析N2O排放贡献,因无需添加标记物、对土壤系统干扰小、成本低,适合在野外田间研究N2O排放,是15N标记方法的有力补充。本文详细介绍了N2O同位素异位体法的原理、质谱测定方法、定量分析方法、影响该方法的因素及其应用前景。

    Abstract:

    Soil is one of the important sources of N2O emissions. Soil N2O production pathway is numerous and regulated by variety of factors, in-depth analysis of soil N2O production pathway can adopt targeted emission reduction strategies. Stable isotope technology has been widely used to the study of soil N2O emissions, N2O isotope method is an emerging research method in recent years. This method analyzes N2O emission contribution by measuring the isotope composition of soil N2O (δ15NSPN2O, δ18ON2O and δ15NbulkN2O), because not need to add markers, little interference to soil system and low in cost, it is suitable for field research on N2O emissions and is a powerful supplement to 15N labeling method. This paper introduces in detail the principle of N2O isotope method, mass spectrometry method and quantitative analysis method, the factors affecting the method and its application prospect.
