Holocene fire history in Northern Germany, inferred from peat and sediment charcoal records with various spatial resolution in selected areas of Schleswig-Holstein

要了解生态系统的动态，重要的是要考虑过去火灾发生的作用。古火作为生态系统的扰动事件，在全新世可能对植被的建立和变化产生了重要影响。虽然这在地中海或北方地区是众所周知的，但火在中欧生态系统中的作用却鲜为人知。本研究试图通过分析德国北部石勒苏益格-荷尔斯泰因两个选定地区不同古档案背景下的木炭记录，在当地和区域尺度上重建火灾历史。不同类型的木炭记录-泥炭和湖泊沉积物序列的微观和宏观木炭，以及土壤中的巨型木炭被放在一个合理的年代学框架内，并对这些记录进行比较，以检测火灾历史中是否存在同步性，这可能允许假设关于人类对当地和区域火灾历史的影响的合理假设。结合不同方法的新方法将在该项目中进行测试，并将为未来全新世火灾历史的研究提供有价值的信息。

To understand the dynamics of ecosystems it is important consider the role of past fire occurences. Palaeofires might have had an important influence on vegetation establishment and change during the Holocene as disturbance event of the ecosystem. While this is well known for Mediterranean or Boreal areas, the role of fire in central European ecosystems is less understood. This research project at-tempts to reconstruct the fire history at a local and regional scale by the analysis of charcoal records from different contexts of palaeo-archives in two selected areas in Schleswig-Holstein, Northern Ger-many. Different types of charcoal records - microand macro-charcoal from peat and lake sediment sequences, as well as mega-charcoals from soils are put in a sound chronological framework and the records are compared to detect the presence/absence of synchronicity in the fire history, which might allow to postulate a sound hypothesis concerning the human influence on the local as well as regional fire history. The new approach combining different methods will be tested in the project and will give valuable information for future research into Holocene fire history.
