Large volcanic eruption is an important factor affecting global climate change. In the past few decades, many researchers reconstructed a number of climate series based on tree rings on the Tibetan Plateau, and examined the impacts of large volcanic eruptions on the climate. The results showed that these tree-ring sites used to examined the influences of large volcanic eruptions on climate change were primarily located in the eastern Tibetan Plateau. In addition, the series comparison and the superposed epoch analysis were main methods for studying the climate effects of large volcanic eruptions. Based on the results analyzed using two methods, we suggested that the large volcanic eruptions in low-mid latitudes had a significant impact on temperature and dry/wet variation. Cooling or drought occurred after large volcanic eruptions in the subsequent 1-2 years. How-ever, the large volcanic eruptions in high latitudes had minor impacts on climate change. Furthermore, consecutive multiple volcanic eruptions could result in cooling at the decades scale. The factors influencing the climate effects of large volcanic eruptions included the location of the volcanic eruptions, intensity of the volcanic eruptions, atmospheric circulation, . Finally, we proposed research projects that need to be carried out in the future.
大规模火山喷发是影响全球气候变化的一个重要因素。在过去几十年里，许多研究人员基于青藏高原的树木年轮重建了一些气候序列，并研究了大规模火山喷发对气候的影响。结果表明，这些用于研究大规模火山喷发对气候变化影响的树木年轮站点主要位于青藏高原东部。此外，序列比较和叠加周期分析是研究大规模火山喷发气候效应的主要方法。基于用这两种方法分析的结果，我们认为中低纬度地区的大规模火山喷发对温度和干湿变化有显著影响。大规模火山喷发后的1至2年出现降温或干旱。然而，高纬度地区的大规模火山喷发对气候变化的影响较小。此外，连续多次火山喷发可能导致数十年尺度的降温。影响大规模火山喷发气候效应的因素包括火山喷发的地点、火山喷发的强度、大气环流等。最后，我们提出了未来需要开展的研究项目。
