    摘要
  • 摘要: 通过对长江中游和尚洞HS-2号石笋的沉积特征及C、O同位素Mg、Sr微量元素相结合分析,利用U系法定年,获取了长江中游19.0ka～6.9ka的古气候、古环境信息(平均分辨率为17a,局部分辨率达到7a).得出如下结论(1)19.0～16.6ka, C、O同位素偏轻,气候冷湿;(2)16.6～11.1ka, C、O同位素偏重, 气温上升,降水偏少;(3)11.1～10.3ka 干热时期中的突然回冷事件对应于新仙女木事件(Younger Dryas Event);(4)10.3～6.9 ka B.P δ18O及δ13C值逐渐变轻,而Mg/Sr比继续增大,表现为气温上升,降雨量较大.反映了历史时期湿冷、干热、湿暖交替变化的气候趋势,得出了长江中游千年级和百年级的一些气候变化趋势,特别是发现了新仙女木事件在长江中游洞穴石笋中完整的记录,说明新仙女木事件是全球性气候突变与环境灾变事件
    Abstract: Through a combined analysis of sedimentary characteristics,C and Oisotopes,Mg and Sr trace elements of a stalagmite from Heshang Cave,Hubei,Wit h urani um-series dating，t he palaeoclimatic and palaeoenvironmental Information from19.0ka to 6.9ka i n the Hubei area is obtained.The average resolution is 17a,and t he local resolution is 7a. The following results are obtained ：(1)f rom 19.0 ~16.6ka B.P. ：C and Oisotopes Were lighter,the climate Was cold and Wet ；(2)16.6 ~11.1kaB.P. ：C，Oisotopes Were a little heavy,temperature rose,r ain fall Was inclined to be little ；(3)11.1 ~10.3ka B.P. ：an excursion during dry and hot period responded to the Younger Dryas Event ；(4)10.3 ~6.9 ka B.P：C，O，I sotopes Were lighter,but Mg/Sr value Was bigger,showing temperature Was continuously rising and rain f all Was greater. These reflect the variation tends from humid-cold climate，to dry- hot climate，and to humid,War mcli mate in history,and some climatic variation trends of thousand years and hundred years cycles are gainned. I n particular the authors found out the integrated record of the Younger Dryas Event Which means the Younger Dryas Event is a globally climatic sudden change and environmental calamity.
