海南北部近2000年气候环境变化——来自双池玛珥湖高分辨率沉积记录
|
摘要
利用海南双池玛珥湖沉积物的粒度、色度、磁化率及干密度等指标重建了该地区~2 007cal a BP以来的环境和气候变化。在2 007~1 413cal a BP期间,气候炎湿,植被覆盖度高,蒸发较强,湖盆近沼泽化;1 413~974cal a BP期间,湖泊水位较高,气候温干,植被覆盖率较低,初级生产力降低;974~468cal a BP期间,气候暖湿,降水渐增,湖区生产力增加,人类活动明显增强;468~184cal a BP期间,气候相对湿热,湖深微有增加,人类活动在该阶段达到峰值;184cal a BP以来,气候相对温和,降水较上阶段减少,湖深不断下降,湖盆生产力不断降低。指标记录可识别出"中世纪暖期"(750~1 250AD)和"小冰期"(1 250~1 750AD),"小冰期"相对较湿润的气候条件与中国南方的湖泊记录具有一致性。
This study presents the record of paleoenvironmental evolution results from a radiocarbon-dated 565-cm-long lacustrine sediment sequence in Shuangchi Maar Lake.Measurements of grain size,magnetic susceptibility(MS),water content,dry density and color reflectance values have been carried out for reconstructing the climate since ~2007 cal a BP.Five distinct stages can be identified as follows.2007-1413 cal a BP,the hot-humid climate was dominated this area and the lake level was shallow.The interval from 1413-974 cal a BP was characterized by a relatively high lake level and mild climate.974-468 cal a BP,it was a relatively humid climate with strong human activities.468-184 cal a BP,this stage had the decreasing precipitation with increasing human activities.since 184 cal a BP,the climate was mild and the water depth was continuously reducing during this period.Relatively dryer MWP(750-1250AD)and wetter LIA(1250-1750AD)could be detected in this sequence,which are consistent with the records of the lakes in South China.
