摘要
摘要:丰富的历史文献是我国过去全球变化研究的优势条件，然在"中世纪暖期"前期，中国东部地区此类别资料中客观而具有高置信度的物候信息仍有深入挖掘的余地。为弥补这一缺憾，根据5种历史文献记载的河南开封、洛阳地区981~1040年的38条赏花日期记录，重建了这60年间开封牡丹盛花期的变化，并将其与其他文献证据、温度重建序列所反映的气候冷暖变化特征进行了对比，检验了资料的准确性。结果显示：1）开封981~1040年的气候可能略暖于现今，牡丹盛花期的均值4月21日比现今早1.0天；2）当时开封牡丹盛花期的变幅（4月11~30日）基本上未超过现代；3）牡丹盛花期呈现出0.4天/10年的微弱提前趋势，说明当时气候虽然总体上偏暖，但增温趋势不明显；4）牡丹盛花期的年代际变化可划分为平均比现今晚1.6天的981~994年、早2.8天的995~1016年、晚2.9天的1017~1030年和早6.0天的1031~1040年这4个阶段，说明当时总体上略比现今温暖的气候并不是持续温暖的；5）序列与夏秋税征收日期、水稻种植范围、柑橘分布北界、植物二次开花与再实、冬雷等其他文献证据所指示的期内各阶段气候状况比较吻合，也与中国东部及邻近地区的其他温度重建序列在冷暖变化过程上异同互现。该结果有助于更为准确地诊断中国东部"中世纪暖期"的阶段性气候变化特征，为下一步集成重建中国东部地区在"中世纪暖期"时段更长、结果不确定性更小的温度序列以及定量分析当时气候变化与社会经济兴衰之间的关系提供重要依据。

Abstract:Abundant historical references are great advantage in the research field of past global changes in China. However, in the early period of the Medieval Warm Period, there is still room for further exploration of objective and high confidence phenological information in Eastern China. In order to fill in this gap, we extracted 38 peony(Paeonia suffruticosa) flower appreciation dates from five kind of historical documents, during 981~1040 A.D., around Kaifeng(34.80°N, 114.32°E) and Luoyang(34.68°N, 112.44°E) in Henan Province. On the basis of the panel data model reflecting the quantitative relationship between spring temperatures and peony full-bloom dates, full-bloom-date variations of peony in Kaifeng at that time were reconstructed. This reconstructed sequence was analyzed by use of the Shapiro-Wilk normality test, Theil-Sen estimator, Mann-Kendall trend test, and the FFT low-pass filter smoothing. The sequence was also compared with other literature evidences and temperature reconstruction series in China.
The analysis showed:(1) The mean full-bloom date in Kaifeng during 981~1040 A.D. was April 21, 1.0 day earlier than the date in 1951~1980 A.D., indicating that the climate in Kaifeng at that time was a little bit warmer than at present. (2) The variation amplitude of full-bloom dates of peony in Kaifeng at that time was between April 11 and April 30, which were very close to the same index at present. (3) This peony full-bloom-date series showed an insignificant advancing trend of 0.4 days/10 a, indicating that the warming at that time was not obvious. (4) Inter-decadal variations of this series could be divided into four phases, including 981~994 A.D., 995~1016 A.D., 1017~1030 A.D. and 1031~1040 A.D., whose mean full-bloom dates was 1.6 days later, 2.8 days earlier, 2.9 days later and 6.0 days earlier than that at present, respectively. (5) The series agrees very well with other multi-category document evidences and temperature reconstruction series, but there are still some differences between them on the climate conditions of the above four sub-periods.
This result provides an important basis for the future integrated reconstruction of an archives-based reconstruction of climate series in Eastern China during the Medieval Warm Period, with a longer time and less uncertainty in the temperature variation. Moreover, it is helpful for a better understanding of the relationship between climate changes and socio-economic fluctuations at that time.
