ABSTRACT
The study objective was to prepare a quantitative inventory of lakes and to assess their long-term changes. The research area included the Osa river basin (northern Poland), which is located in a lake district. The research was based on historical cartographic materials published in 1900-1947 (German 1:25,000 ‘Messtischblatt’ topographic maps) and modern topographic maps from 2010 (The 1:50,000 Digital Map of the Hydrographic Division of Poland [MPHP]. The number of lakes increased from 173 to 235, while the total surface area of the lakes fell by 107.55 ha. The largest number of lakes belonged to the 1.0-5.0 ha range on both MPHP and Messtischblatt maps. It was in this range that the largest increase in number of lakes and lake area relative to the historical maps was found. A significant reduction in area of lakes was recorded in the group of lakes with an area from 50 to 100 ha.

摘要
研究目标是编制湖泊的定量清单并评估其长期变化。研究区域包括位于湖区的奥萨河流域(波兰北部)。该研究基于 1900-1947 年出版的历史制图材料(德语 1:25,000 'Messtischblatt' 地形图)和 2010 年的现代地形图(波兰水文局 [MPHP] 的 1:50,000 数字地图)。湖泊从 173 个增加到 235 个,而湖泊总面积减少了 107.55 公顷。在 MPHP 和 Messtischblatt 地图上,湖泊数量最多都在 1.0-5.0 公顷范围内。在这个范围内,湖泊的增加幅度最大。找到了相对于历史地图的湖泊数量和湖泊面积。
