| 摘 要： | 通过对福建北部天湖山泥炭沉积记录的有机质含量和腐殖化度等多种环境代用指标的综合分析,在可靠14C测年技术的支持下,恢复了福建北部天湖山近10cal kyr BP以来的气候与环境演变过程.结果发现,泥炭有机含量和腐殖化度敏感地记录了研究区古气候变化信息,其低值指示气候相对暖湿,高值指示气候相对冷干.约10～4cal kyr BP泥炭有机质含量和腐殖化度较高,指示气候暖湿,是该区域水热组合状况最好;4cal kyr BP以来泥炭有机质含量和腐殖化度较低,指示气候相对干冷.细分千年尺度的气候变化阶段有待于测年精度的进一步提高.

| Abstract: | Organic content and humification as two climatic proxies were used for the first time to study Tianhu Mountain peat.They have better recorded the climate change in the northern Fujian.Based on the synthesis of the multiply indexes from the Tianhu Mountain peat sequence which obtained from the northern Fujian and the reliable testing of the radiocarbon ages,the variations of the paleo-climate in the northern Fujian during the past 10 cal kry BP were reconstructed.The study shows that the humification is an ideal proxy for pale climatic changes,the low value of organic content and humificaion indicates humid-warm climate,and low value implies dry-cold climate.The phase about 10 to 4 cal kyr BP of low organic content and humification,indicating warm and moist climate,the phase about 4 to 0 cal kry BP of high organic content and humification,suggesting a cool and moist climate. |
