【摘要】 大兴安岭摩天岭泥炭藓泥炭纤维素的δ13C时间序列揭示了近1000a来该区气候的演变过程。区内1000a的气候经历了950700aBP、700300aBP及300aBP以来三个阶段百年尺度的干湿波动,这些波动上又叠加了一系列数十年尺度的气候变化。该序列指示了大兴安岭地区近代气候向着偏干方向发展。更多还原

【Abstract】 The peat cellulose δ¹³C sequence in Daxing Anling reveals 1ka of climate change in Northeast China. During the period of 950⁷00 a BP, 700³00 a BP,300 a BP to present, 3 climate fluctuation of centennial scale are developed in Daxing Anling. The coincident results are got from the peat pollen analysis and from Jinchuan peat. Our study indicated that the recent clinate in Daxing Anling area became drier and drier.更多还原
