Abstract
利用大量的古多年冻土遗迹和古冰缘现象, 并佐以古冰川、孢粉及动物化石等资料, 重建了20ka以来中国多年冻土演化进程. 结果表明, 在末次冰期最盛期(LGM, 或末次多年冻土最大期LPMax), 中国多年冻土面积达到了5.3<x content-type="symbol">´</x>10<sup>6</sup><x content-type="symbol">~</x>5.4<x content-type="symbol">´</x>10<sup>6</sup>km<sup>2</sup>(现今中国多年冻土面积的3倍多), 而全新世大暖期(HMP, 或末次多年冻土最小期LPMin), 中国多年冻土面积曾缩减至0.80<x content-type="symbol">´</x>10<sup>6</sup><x content-type="symbol">~</x>0.85<x content-type="symbol">´</x>10<sup>6</sup>km<sup>2</sup>(约为现今中国多年冻土面积的50%). 按照古冻土遗迹的年代及分布等特征, 在确定LGM和HMP两个主要时段的冻土格局基础上, 将20ka以来中国多年冻土演化进程划分为7个阶段: 晚更新世LGM(20000<x content-type="symbol">~</x>10800aBP)多年冻土强烈扩展, 达到LPMax; 早全新世气候剧变期(10800至8500~7000aBP)多年冻土较稳定但相对缩减阶段; 中全新世HMP(8500~7000至4000~3000aBP)多年冻土强烈退化阶段, 多年冻土缩减到LPMin; 晚全新世新冰期(4000~3000至1000aBP)冻土扩展阶段; 晚全新世中世纪暖期(1000<x content-type="symbol">~</x>500aBP)多年冻土相对退化阶段; 晚全新世小冰期(LIA, 500<x content-type="symbol">~</x>100aBP)冻土相对扩展阶段, 以及近代升温期(近百年来)多年冻土持续退化阶段. 本文重建了各时段内古气候、古地理环境以及多年冻土分布范围和其他特征.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
