摘要了解北方森林的长期生态动态对于评估森林生态系统对气候变化的可能响应和反馈是至关重要的。过去的森林动态和泥炭地发展的新数据，从泥炭序列在南部瓦尔代丘陵（欧洲俄罗斯）的基础上花粉，植物宏化石，微木炭，泥炭腐殖化，和有遗嘱的变形虫分析。结果表明，阔叶林在研究区域从7000-4000卡年BP的优势。云杉最初是这个森林的一个次要组成部分，但在覆盖迅速增加，气候变冷开始在4000卡年BP，成为优势物种。阔叶树种持续到900卡年BP，有证据表明，近几个世纪以来，加强砍伐和森林管理。在过去的400年里，有证据表明广泛的沼泽化和云杉泥炭藓森林的建立。这些数据表明，现代潮湿的林地是如何在数千年的气候和人为因素的共同作用下形成的。研究结果还表明了多代理方法在了解长期森林生态方面的价值。
Abstract Understanding the long-term ecological dynamics of boreal forests is essential for assessment of the possible responses and feedbacks of forest ecosystems to climate change. New data on past forest dynamics and peatland development were obtained from a peat sequence in the southern Valdai Hills (European Russia) based on pollen, plant macrofossil, micro-charcoal, peat humification, and testate amoeba analyses. The results demonstrate a dominance of broadleaved forests in the study area from 7000–4000 cal yr BP. Picea was initially a minor component of this forest but increased in cover rapidly with climatic cooling beginning at 4000 cal yr BP, becoming the dominant species. Broadleaved species persisted until 900 cal yr BP, with evidence for intensified felling and forest management over recent centuries. Over the last four hundred years there is evidence for widespread paludification and the establishment of Picea-Sphagnum forests. These data demonstrate how modern wet woodlands have been shaped by a combination of climatic and anthropogenic factors over several millennia. The results also demonstrate the value of a multiproxy approach in understanding long-term forest ecology.
