摘　　要：太阳总辐照度(TSI)变化是影响地球气候变化的重要因素,对TSI的监测与重建是研究太阳活动驱动全球气候变化机制的重要基础。本文回顾了地基平台和卫星平台的TSI监测历程及其取得的主要研究成果,分析了利用宇宙成因核素和地外天体信息重建TSI的研究进展及所存在的问题,并对该领域未来的发展方向进行展望。现有的地基平台和卫星平台TSI监测资料表明,太阳活动周期中TSI的变化幅度很小,不足以引起各种记录中所观测到的气候变化。但太阳物理领域迄今尚未完全解译TSI变化的物理过程,加之TSI监测资料所限,难以判定其过去或未来的变幅,需整合现有3种主要的数据合成方法,并继续坚持TSI长期监测。此外,还需利用宇宙成因核素、地外天体信息反演等新方法重建过去太阳活动所造成的TSI变化,以获得长周期TSI变化序列。Total Solar Irradiance （TSI） is defined as total energy of electromagnetic radiation of all bands from the sun to any sphere （including the Earth＇s surface） in per unit area and per unit time. Change of TSI in solar active cycle has been considered as one of important candidate factors impacting global climate change. Monitoring and reconstruction of TSI is the important foundation for the study of the mechanism of how solar activities drive global climate change. In this article, we first reviewed the history of both ground-based and satellite-based TSI monitoring and the results they produced. Then, we analyzed the research progress on, and the problems in, using cosmogenic nuclides and celestial information to reconstruct TSI series. Finally, we provided an outlook of future directions in this field. Existing ground-based and satellite-based TSI monitoring has access to lots of TSI series of different time-scales and temporal resolution. The TSI monitoring data shows that TSI changes very little in each solar activity cycle, not enough to cause the earth surface temperature rise observed and documented in a variety of records. However, solar physics has not yet fully interpreted the physical process of TSI change, and, with limited TSI monitoring data, it is difficult to find out the mechanism of how solar activities cause TSI changes and drive the climate change. It is also impossible to accurately determine the variations of the past or future solar activities and TSI. In addition, due to instrument capacity, service time, monitoring environment and other objective factors, the TSI data has many uncertainties. Therefore, it is necessary to continue exploring the mechanism of solar activities and the TSI change, develop higher precision equipment, integrate different data composite methods, such as ACRIM, PMOD, and IRMB, and adhere to long-term TSI monitoring. In addition, use of cosmogenic nuclides such as 10Be and 14C in reconstructing TSI change caused by solar activity is also necessary to obtai
