【摘要】 陆地生态系统的碳循环过程中最活跃的碳库是农田生态系统。农田生态系统碳循环模型是研究碳循环的重要方法之一。简要介绍了碳素在不同碳库之间迁移转化的规律,阐述了农田生态系统碳循环模型的发展历程以及国内外主要的碳循环模型,并对未来农田生态系统碳循环模型研究趋势进行了展望,以期为减少农业面源污染、温室气体排放和研究全球气候变化提供科学依据。更多还原

【Abstract】 The most active carbon pool in terrestrial ecosystems carbon cycle is the farmland ecosystem. The carbon cycle model of farmland ecosystem is one of the important methods to study carbon cycle. The law of migration and transformation of carbon between different carbon pools briefly were introduced, the development process of the carbon cycle model of farmland ecosystem was explained, the main carbon cycle modes at home and abroad were reviewed, the research trend of carbon cycle model of farmland ecosystem in the future is prospected. This will provide a scientific basis for reducing agricultural source pollution, greenhouse gas emissions, and studying global climate change.更多还原
