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.

为了了解生态系统的动态，重要的是考虑过去火灾的作用。古火作为生态系统的扰动事件，可能对全新世植被的建立和变化产生重要影响。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。本研究试图通过对北方德国石勒苏益格-荷尔斯泰因州两个地区不同背景的古档案中木炭记录的分析，重建当地和区域尺度的火灾历史。不同类型的木炭记录-微观和宏观木炭从泥炭和湖泊沉积物序列，以及从土壤中的mega-charcoals放在一个健全的年代框架和记录进行比较，以检测存在/不存在的同步性的火灾历史，这可能允许假设一个健全的假设，关于人类对当地以及区域火灾历史的影响。结合不同方法的新方法将在该项目中进行测试，并将为未来研究全新世火灾历史提供有价值的信息。
