| 总结了农田生态系统温室气体的主要来源、排放特征，以及国内外相关监测标准体系。综述了静态箱法、涡度相关法、便携式光谱仪监测法和卫星遥感技术的发展历程、优点和局限性，指出农田生态系统温室气体监测方法在应用实施中存在监测效率低、成本高、环境干扰多等问题，建议未来进一步研发低成本传感器和自动化技术，推动卫星遥感技术与人工智能深度融合，加快农田生态系统温室气体区域监测网络构建。 |
| 英文摘要: |
| This article summarized the major sources and emission characteristics of greenhouse gases in farmland ecosystem and the relevant monitoring standard systems at home and abroad， reviewed the development history， advantages and limitations of static chamber technique， eddy covariance technique， portable spectrometer monitoring and satellite remote sensing technology. It pointed out the problems such as low monitoring efficiency， high cost and numerous environmental interference existing in the application of monitoring methods for greenhouse gas in farmland ecosystem. It suggested carrying out further research and development of low cost sensors and automation technologies， promoting deep integration of satellite remote sensing technology and artificial intelligence， and strengthening the construction of regional monitoring networks for greenhouse gases in farmland ecosystems in the future. |
