利用熟知的山洞石笋资料及重建的太阳黑子数获取的时间序列，讨论了长时间尺度上气候对太阳活动变化的可能响应。小波分析显示气候变化与太阳活动变化在约1000及约2000年周期上具有一致性，这可能反映了全新世时期太阳活动的调制作用。另外，小波功率谱显示在公元前2000年附近缺失千年周期，这种突变及气候条件的长期变化可能给许多地区带来社会性影响。

Based on well-known series from land-based caves and reconstructed sunspot numbers, the nature of climatic response to solar variability is discussed over a long-time scale. Wavelet analysis reveals coherence between the climatic and solar oscillations with periods of~1000-and~2000-yr that may relfect a modulation of solar activity during the Holocene. Moreover, the wavelet power spectra present that~1000-yr cycle of these series is absent around~2000 BC and this abrupt change and prolonged changes in climatic conditions might have brought about major societal challenges to many regions.
