黄土高原高山湖泊沉积记录的近2000年来六盘山南北两侧气候与环境差异
Loess Plateau alpine lake sediment records of nearly 2,000 years Liupanshan differences north and south sides of the climate and environment
位于黄土高原西部的六盘山地区是重要的人类文明发源地之一，由于地处黄土高原，该区域缺乏高分辨率的气候与环境变化记录。本文对六盘山南北两侧的后湫与北联池两个高山湖泊近2000年来的湖泊沉积记录进行了研究，通过磁化率、粒度、TOC等多指标分析结果，结合碳十四AMS测年, 重建了较为可靠的近2000年来的气候变化记录。通过对以上记录的分析，初步判定六盘山南北两侧气候差异较大，而造成差异的主要影响因素还需进一步的研究。
Liupan mountain is one of the important region of cradles of human civilization in west of loess plateau region. this region lacks high-resolution record of climate and environmental changes . In this paper, we choose two high mountain lakes located on north and south sides of Liupan mountain. and nearly 2,000 years record from lake sediments have been studied by magnetic susceptibility , grain size , TOC and other multi-index analysis , combined with carbon-14 AMS dating , a more reliable reconstruction of past climate change in past 2000 years was recorded. Recorded by the above analysis, the preliminary determination shows Liupan mountain climate is quite different between north and south sides , while the main factors causing differences need further study.
