| 摘要: |
| 厄尔尼诺-南方涛动（ENSO）是海洋-大气耦合系统中最强的年际气候变化信号，对热带乃至全球的气候均具有重要影响。然而受限于较短的现代器测资料，目前对于ENSO活动的机制、影响及未来预测仍存在很大的不确定性。高分辨率古气候数据为更准确地认知ENSO变化提供了重要线索，但由于气候代用记录和重建方法的不确定性导致目前对全新世ENSO活动的特征和机理仍存在争议。收集目前已发表的238条全新世ENSO重建代用记录（存储格式为.xlsx），汇总这些记录的经纬度、载体类型、分辨率及指示意义等基本信息，在此基础上，选取中、东太平洋（ENSO活动的核心区域）片段式的ENSO重建代用序列进行可靠性评估，集成重建了一条全新世ENSO变化序列。结果表明全新世中期ENSO活动相对较为平稳，全新世晚期ENSO活动的强度和频率均增强。对现有的ENSO重建结果进行讨论和评估，有助于深入理解不同重建结果之间的差异，为更精确地认识ENSO变化规律提供整合性的证据支持。 |

| Abstract: |
| The El Niño-Southern Oscillation (ENSO) is the strongest signal of interannual climate variability in the ocean-atmosphere coupled system, exerting broad regional impacts on both tropical and global climates. However, limited by the relatively short duration of modern instrumental records, there remains considerable uncertainty in the study of ENSO mechanisms, impacts, and for future predictions. High-resolution paleoclimate data offers crucial insights for a more complete understanding of ENSO variability. Yet, uncertainties in climate proxy records and reconstruction methods have led to ongoing debates regarding the characteristics and mechanisms of Holocene ENSO activity. This report compiles 238 published Holocene ENSO reconstruction records (stored in .xlsx format), summarizing key information such as their latitude and longitude, proxy types, time resolution, and indicative significance of each record. On this basis, segmented ENSO reconstruction sequences from the central and eastern Pacific (the core regions of ENSO activity) were selected for reliability assessment, leading to an integrated reconstruction of a Holocene ENSO variability sequence. The results indicate that ENSO activity remained relatively stable during the Mid-Holocene, while its intensity and frequency have increased since the Late Holocene. A discussion and evaluation of the existing ENSO reconstruction results helps to better understand the similarities and differences between various reconstructions, providing integrative evidence to more precisely comprehend the patterns of ENSO variability. |
