摘　　要：陆地生态系统通过植被光合作用可以吸收约30%的人为碳排放,在全球碳循环、减缓大气二氧化碳浓度上升等方面具有重要作用。最近10年发展起来的日光诱导叶绿素荧光遥感技术,可以监测植被实际光合作用,为全球陆地生态系统碳循环的研究提供了新的思路和方法。本文回顾了叶绿素荧光遥感产品发展及其在陆地生态系统碳循环和陆气相互作用中的应用研究进展,特别是在全球植被总初级生产力估算和陆地生态系统碳循环模型发展方面的进展,并进一步讨论了该领域研究面临的挑战和未来的发展方向。The terrestrial ecosystem can absorb about 30%of the anthropogenic carbon emissions through vegetation photosynthesis,which plays an important role in the global carbon cycle and slowing the rise of atmospheric carbon dioxide concentration.The solar-induced chlorophyll fluorescence(SIF)remote sensing technology developed in the last 10 years can monitor the actual photosynthesis of vegetation,providing new ideas and methods for the study of global terrestrial ecosystem carbon cycle.This paper reviews the recent progresses in the study of satellite-based SIF observations and their applications in terrestrial ecosystem carbon cycling and land-atmosphere interaction,especially in the estimation of global vegetation gross primary productivity and the development of terrestrial ecosystem carbon cycle models,and further discusses the challenges faced by research in this field and the future development directions.
