Understanding about regional versus local changes in vegetation is critical in answering archaeological questions, in particular at a time when humans are assumed to have caused higher disturbances at local scales rather than regional scales; this is the case during the Neolithic. The aim of this paper is to assess the impact of Neolithic land use on regional and local vegetation dynamics, plant composition and disturbance processes (e.g. fire) in eastern Fennoscandia. We apply the Landscape Reconstruction Algorithm (LRA) to high-resolution pollen records from three lacustrine sediment cores that cover the Neolithic period. We calculate changes in vegetation composition and the rate of plant compositional change. Fire dynamics are estimated as an indicator of land use, although fire can result from both natural and anthropogenic disturbances. Our results show that during the Early Neolithic, changes were mainly driven by natural and climate-induced factors and vegetation composition and fire activity were similar at both regional and local scales. From ca. 4000 bc onwards, trends in vegetation and fire dynamics start to differ between regional and local scales. This is due to local land uses that are overshadowed at the regional scale by climate-induced factors. The use of the LOVE model in pollen analyses is therefore very useful to highlight local land uses that are not visible by using REVEALS.

了解植被的区域变化与局部变化对于回答考古问题至关重要，尤其是在人们认为人类在地方尺度而非区域尺度造成了更大干扰的时候；新石器时代就是这种情况。本文的目的是评估新石器时代土地利用对东部芬诺斯坎迪亚地区和当地植被动态，植物组成和干扰过程（例如火灾）的影响。我们将景观重建算法（LRA）应用于覆盖新石器时代的三个湖相沉积岩心的高分辨率花粉记录。我们计算植被组成的变化和植物组成的变化率。尽管自然和人为干扰均可引起火灾，但火灾的动态估计可作为土地使用的指标。我们的研究结果表明，在新石器时代早期，变化主要是由自然和气候引起的因素驱动的，区域和地方尺度的植被组成和火灾活动相似。从大约 4000从公元前开始，区域和地方尺度之间植被和火灾动态的趋势开始有所不同。这是由于当地的土地利用在区域范围内被气候诱发的因素所掩盖。因此，在花粉分析中使用LOVE模型对于突出显示REVEALS无法看到的当地土地用途非常有用。
