在我国沙漠_黄土过渡带分别研究了榆林蔡家沟、横山石峁、会宁李家塬和定边姬塬 4个黄土剖面 ,得到过去 130ka来高分辨率的古气候变化记录 ,并从中识别出轨道尺度、万年左右尺度、千年尺度和千年至百年尺度这 4类古气候事件 ;运用最新研制的“自动轨道调谐时间标尺” ,分别估计了这些事件所发生的时代 ,并由此建立了黄土高原地区过去 130ka来古气候事件年表 . Four loess profiles of Caijiagou, Hengshan Shijie, Lijiayuan and Dingbian Jiyuan in Yulin have been studied in the desert-loess transitional zone, respectively, and the high-resolution palaeoclimate records of the past 130 ka have been obtained and the orbits have been identified Scale, thousand years scale, thousand years scale and thousand years to hundred years scale. Using the latest developed “automatic orbit tuning time scale”, we respectively estimate the times of these events and establish the Loess Plateau Regional past 130ka paleoclimate event chronology.
