摘　　要：为明确海北藏族自治州农业生产中温室气体排放的时空变化情况,运用生命周期评价方法对海北州的农作物播种面积、产量、农资投入情况及其产生的温室气体排放量进行分析。结果表明,海北州种植结构发生了较大变化,粮食作物向油料作物转变,门源地区农资投入量最高,温室气体排放量也最高,约占75.0%,并且氮肥的生产和使用是造成温室气体排放的主要原因,约占总排放的88.8%。因此,海北州需重点关注门源地区农作物生产的管理过程,尤其是氮肥管理。In order to clarify the temporal and spatial changes of greenhouse gas emissions from agricultural production in Haibei Tibetan Autonomous Prefecture,the life cycle assessment method was used to analyze the sown area,yield,agricultural input and greenhouse gas emissions.The results showed that the planting structure of Haibei prefecture changed greatly,food crops changed to oil crops,and agricultural inputs and greenhouse gas emissions were the highest in Menyuan area,accounting for 75.0%.The production and use of nitrogen fertilizer were the main cause of greenhouse gas emissions,accounting for 88.8%of the total emissions.Therefore,Haibei Prefecture should pay more attention to the management process of crop production in Menyuan area,especially nitrogen fertilizer management.

关 键 词：农资投入 温室气体 氮肥的生产和使用
