Abstract:

植物叶蜡正构烷烃组分能够在地质体中长久保存,并记录历史时期植被变化的信息。本研究通过对黄土高原中部董志塬西峰地区赵家川剖面古土壤中正构烷烃组分的分析,讨论7~2Ma期间黄土高原植被变化的植物叶蜡组分变化特征及其对气候变化的响应。结果表明:从7.0Ma至3.4Ma,正构烷烃C31/C27和C31/C29比值处于相对低值的波动范围,范围分别为0.5~1.9和0.6~1.3,表明该时期以木本植物占优势的生态格局;在3.4Ma前后,古土壤中保存的古植被叶蜡正构烷烃组分的C31/C27和C31/C29比值有一个明显的增加,分别从0.8变化到2.9,从0.7变化至1.6,即古生态系统中草本植物的相对比例突然增加;从3.4Ma至2.0Ma,正构烷烃C31/C27和C31/C29比值处于相对高值的波动范围,范围分别为1.7~3.3和1.1~1.6,指示该时期木本植物减少,草本植物增加的生态格局。我们推测这个生态系统的变化可能响应晚新生代3.5Ma左右的中国内陆干旱化,并形成了自此以后黄土高原塬面以草原或森林草原为主的自然生态格局。
