China is a global hotspot for reactive nitrogen (N) emissions driven by its large livestock sector, which contribute to air pollution, climate change, and biodiversity losses. Despite their importance, current emission inventory development efforts often address singular N species, lacking a comprehensive presentation of all N species together and their interconnected features. This may jeopardize China's achievements of carbon neutrality and clean air. In this study, we developed a high-resolution (0.1° × 0.1°) inventory of monthly N emissions from livestock manure in China for 23 livestock types from 2005 to 2022. Based on a unified dataset, our inventory provides detailed estimates of multiple N emissions from livestock, including ammonia, nitrogen oxides, and nitrous oxide. The inventory can serve as a valuable resource for atmospheric modelling and support integrated nitrogen management strategies in response to China's evolving agricultural landscape, facilitating future decision-making to tackle environmental challenges associated with the agriculture sector.
由于庞大的畜牧业，中国是活性氮（N）排放的全球热点地区，这导致了空气污染、气候变化和生物多样性丧失。尽管它们很重要，但目前的排放清单编制工作往往只涉及单一的氮物种，缺乏对所有氮物种及其相互关联特征的全面呈现。这可能会危及中国在碳中和和清洁空气方面取得的成就。在本研究中，我们编制了一份2005年至2022年期间中国23种牲畜类型的畜禽粪便月度氮排放高分辨率（0.1°×0.1°）清单。基于统一的数据集，我们的清单提供了来自牲畜的多种氮排放的详细估算，包括氨、氮氧化物和一氧化二氮。该清单可作为大气建模的宝贵资源，并支持针对中国不断变化的农业格局的综合氮管理策略，促进未来应对与农业部门相关环境挑战的决策。
