| 摘 要： | 摘要：根据对长江三角洲南翼第四纪沉积物的磁化率、粒度、地球化学元素、色度等环境指标的综合分析，试图重建该地区全新世气候变化序列，可划分为五个冷暖旋回阶段：1）10．4～8．8kaBP末次冰期结束快速升温的早全新世；2）8．8～5．4kaBP温暖湿润的早中全新世；3）5．4～2．8kaBP频繁波动相对趋冷的中晚全新世；4）2．8～1．2kaBP气候有所回暖的晚全新世；5）1．2～O．4kaBP，气候快速变冷期。在此基础上，与中国西北及其他地区全新世研究成果对比分析，旨在说明长三角沉积物记录的全新世气候变化具有普遍性。

| Abstract: | Depending on magnetic susceptibility, grain size, elemental chemistry, SCR parame- ters to analyze Quaternary sediments in southern wing of the Yangtze River Delta, we try to rebuild the Holocene climate change. Environmental changing sequence can be divided into five stages of war- ming and cooling cycles . 1） 10.4- 8.8kaBP, the rapid warming in the Last Glacial and Early Hol- ocene; 2） 8.8 - 5.4 kaBP, the warm and humid period in the early midHolocene; 3） 5.4-2.8 kaBP, the relative cooling and frequent fluctuations in the midlate-Holocene 4） 2.8 -- 1.2 kaBP, climate warming in the late Holocene; 5） 1.2 - 0.4kaBP, rapid cooling period. The paper is to compare with Holocene research results of other regions and the NW China, to illustrate catholicness of Holocene climate variability model of the Yangtze River Delta. |
