对浙江天目山千亩田泥炭剖面进行了碳同位素测年，建立了泥炭腐殖化和LOI的时间-深度曲线，分析了该地区泥炭腐殖化和LOI的变化，发现两个代用指标具有较好的相关性，并能识别4200 aBP以来的气候变化，主要有三个阶段：早期阶段（4 135±40~3 200 aBP）低腐殖化阶段，气候温暖湿润;中期（3 200~630 aBP）高腐殖化阶段，气候干燥凉爽;晚期（630 aBP以来）低腐殖化阶段，气候凉爽湿润。
Age-depth curves have been constructed using radiocarbon dates for the Qian Mutian peat profile of Tianmu Mountain area,Zhejiang Province.According to the analysis of the peat humification and LOI for this region,we can find that both the proxy indices show good correlation and identify climatic shifts since 4 200 aBP.Mainly there are three phases:early phase(4 135±40~3 200 aBP)of low humification,indicating warm and moist climate;mid phase(3 200~630 aBP) of high humification,showing dry and cool climate;and late phase(since 630 aBP) of low humification,suggesting a cool and moist climate.
