项目摘要

Our inventory of surface N2O emissions has expanded dramatically over the past several decades. Despite the diversity of conditions under which surface emissions have been monitored, we are still challenged to effectively model N2O emissions in the natural environment. Most studies have simply examined surface emissions, treating the soil as a two-dimensional body. Understanding the three-dimensional nature of N2O production and consumption and the resulting surface and sub-surfaces fluxes of N2O are key to modeling this process. This project will collect a series of high temporal resolution data sets to examine N2O production, consumption and emissions of soil profiles under field conditions and based on these findings examine some of the triggers of N2O production and consumption (carbon, water content and temperature) under more controlled conditions in the laboratory. This work will enable the refinement of models of N2O production and transport in the soil profile and allow better prediction of the effects of management, climate and climate change on N2O emissions from ageroecosystems.
在过去的几十年里,我们的地表N2O排放量急剧增加。 尽管监测地表排放的条件多种多样,但我们仍然面临着有效模拟自然环境中N2O排放的挑战。 大多数研究只是简单地检查了表面排放,将土壤视为二维物体。 了解N2O产生和消耗的三维性质以及由此产生的N2O表面和次表面通量是模拟这一过程的关键。 该项目将收集一系列高时间分辨率的数据集,以研究实地条件下土壤剖面的N2O产生、消耗和排放情况,并根据这些研究结果,在实验室更严格控制的条件下研究N2O产生和消耗的一些触发因素(碳、水含量和温度)。 这项工作将有助于完善土壤剖面中一氧化二氮产生和迁移的模型,并能够更好地预测管理、气候和气候变化对农业生态系统一氧化二氮排放的影响。
