报道一种新的、较敏感的古气候代用指标——泥炭腐殖化度.通过与同一剖面木里苔草纤维素δ13C气候代用指标及其他气候代用指标的对比,得出泥炭的腐殖化度可以用作气候变化的代用指标,即:腐殖化度偏大,指示气候偏暖湿;腐殖化度偏小,指示气候偏干冷.由于泥炭腐殖化度测定相对简捷,值得进一步推广研究.
Reported a new and more sensitive indicator of paleoclimate substitution - degree of peat humification.By comparison with the δ13C climatic proxy index and other climatic proxy indicators of Carex lasiocarpa on the same section, the peat humification Degree can be used as a proxy for climate change, namely: the humification is too large, indicating a warm and humid climate; humification degree is too small, indicating that the climate is dry and cold.Determination of peat humility is relatively simple and worthy of further promotion the study.
