| 摘 要： | 利用特征向量分析、时序叠加分析和谱分析相结合的方法，给出了近５０年来我国地面气温场中较为清晰的火山喷发和太阳活动信号。强烈的火山喷发导致全国大部分地区降温，降温最明显的时段是喷发１年多以后，并能持续约半年。除这个主信号以外，青藏高原、东南沿海和东北地区都可能出现较为复杂的温度变化。温度变化与太阳活动之间的联系更多地反映在二者的振荡关系上。

| Abstract: | By use of PCA/SEA and spectrum analysis, the signals of volcanic eruption and solar activity in the variations of the surface air temperature over China in the past 50 years have been described The decrease of temperature appears 15 months later following the eruption and lasts about half year More comprehensive temperature change pattern could be found over the Tibetan Plateau, southeast coast and northeast areas The contact between solar activity and temperature change is more likely related in their co-vacillation characters |
