中文摘要：
以^14C测年为基础，构建了天日山千亩田地区泥炭沼泽剖面年龄深度模式曲线，通过该区的腐殖化度与烧失量分析研究，发现两者呈现出很好的相关性，共同记录了谊地区4200aBP以来的气候变化，可划分出3个主要阶段：早期（4135±40～3200aBP）泥炭腐殖化度偏低，指示气候湿热；中期（3200～630aBP）泥炭腐殖化度偏高，指示气候温凉偏干；晚期（630aBP以来），泥炭腐殖化度偏低，气候温凉湿润。
英文摘要：
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.
