| 摘 要： | 剖析"太阳-气候-水资源"体系作用机制对区域水资源科学管理具有重要科学意义。利用相关分析、主成分分析和小波分析方法，探究太阳黑子运动和厄尔尼诺（ENSO）对日本吉野川流域降雨、地表径流和地下水位影响。研究结果表明:太阳黑子活动和ENSO对研究区域水文过程显著影响分别发生在11 a和2~7 a周期上；太阳黑子运动能量以ENSO为"媒介"作用于流域降水和河川径流，但对地下水位波动影响不明显；太阳黑子活动在不同时频域对研究区域水文过程产生"直接"和"间接"影响，太阳黑子的"直接"影响可能通过调制ENSO外的气候模态来实现，其"间接"作用则通过"ENSO-西太平洋副高-东亚环流-水汽运动"系统作用实现。

| Abstract: | Interpretation on the mechanism involved in the "Sun-Climate-Water" system provides scientific guidance on the water resource management. Using correlation analysis, principal component analysis and wavelet analysis approaches, the combined influences of solar activity and El Niño Southern Oscillation (ENSO) on precipitation, river flow and groundwater levels in Yoshino River basin, Japan were investigated. And the results indicate the following:① Significant influences of solar activity and ENSO on the hydrological processes mainly concentrate in the periodicities of 11 and 2-7 a, respectively. ② The solar-modulated ENSO plays a critical linkage between solar activity and precipitation/surface water resource. However, this linkage doesn't act in the Sun-ENSO-aquifer system. ③ Both direct and indirect influences of solar activity on hydrological processes in the study area are obtained. The direct influence might act via the function of non-ENSO climate indices, while the indirect influence might act via the process of "ENSO-Western Pacific Subtropical High-East Asian Circulation-Water Movement". |
