研究了三个腐殖质湖泊水系植被的历史发展。我们采用多种方法重建了过去的植被（植物宏观遗迹、泥炭分解、沉积物化学和放射性碳测年）。通过植被和水体化学分析，评价了这些湖泊的当代环境。最古老的前滨沉积物形成于13075 ~ 12700 cal BP（苏查尔湖六）、10115 ~ 9670 cal BP（苏查尔湖三）和8747 ~ 8479 cal BP（威德内湖）。现代植被的差异反映在亚化石植物组合上。从一开始，苏查尔3湖附近出现了贫沼和沼泽，苏查尔6湖发育了中富沼和贫沼，而维德内湖发育了芦苇沼泽和中富沼。随着时间的推移，滨前植被发生了变化，但只是在有限的范围内，具体到每个湖泊，对应于湖泊之间的水化学差异。结合湖泊的特定植被和水体参数等特征，将湖泊划分为腐殖质湖泊。然而，在过去的几十年里，不断升级的气候和人为变化可能会改变这些水体的特征。多学科方法的应用可以比较三个表面上相似的湖泊的发展，并确定显著的生态差异。
The historical development of the hydroseral vegetation of three humic lakes was studied. We applied a combination of methods to reconstruct the past vegetation (plant macroscopic remains, peat decomposition, sediment chemistry and radiocarbon dating). The contemporary environment of these lakes was assessed by vegetation and water chemistry analyses. The oldest foreshore sediments were formed 13075–12700 cal BP (Lake Suchar VI), 10115–9670 cal BP (Lake Suchar III) and 8747–8479 cal BP (Lake Widne). The differences in contemporary vegetation are reflected in the subfossil plant assemblages. From the beginning, poor fens and bogs occurred beside Lake Suchar III, moderately rich and poor fens were developed at Lake Suchar VI, while reedswamps and moderately rich fens occurred at Lake Widne. The foreshore vegetation changed over time but only within a restricted range, specific for each lake corresponding to the hydrochemical differences between the lakes. Lakes are classified as humic if some features are combined, such as the specific vegetation and water parameters. However, over the past few decades escalating climatic and anthropogenic changes could transform the character of these water bodies. The application of multidisciplinary methods permitted comparison of the development of three apparently similar lakes and identification of significant ecological differences.
