黄河下游历史时期环境变化的烧失量记录
|
摘要
基于精确14C测年,对黄河下游地区湖泊沉积物岩芯的烧失量进行了分析,结合历史文献资料重建了该区域的气候环境演变历史.研究表明,黄河下游地区沉积物烧失量指示了数次冷暖干湿的大环境变化:2400-1600aBP期间,气候较为温暖,后期转冷;1600-1000aBP期间,气候波动较为复杂,间或有冷暖交替现象;1000aBP至今,气候以暖湿为主,中期有较大波动.
We demonstrate the LOI of cores of floodplain aggradation in the lower Yellow River,using the method of documents and materials' research to study the information in area based on detailed 14C dating,rebuilding the climate environment evolution history of the region. The results indicate that the LOI of floodplain aggradation in the lower Yellow River has several climate transitions: During 2400-1600 aBP,climate is warmer,and the late become cold and dry; From 1600-1000 aBP,climate fluctuations is relatively complex,or changes in temperature of alternate phenomenon; From 1000 aBP to now,the regional climate is warm and wet,but medium-term has a remarkable fluctuation.
