The occurrence of springs in the European Lowlands has not yet been satisfactorily recognised. This is because crenological research focuses mainly on mountainous areas, where springs are common and rich in water. The premise to undertake research on the springs of lowland and postglacial areas in Poland is the fact that they allow the assessment of spring abundance in the areas with geological structure and hydrological conditions different than in the mountains, which is now an extremely important argument. The study presents preliminary results of research on Roztoka Springs, located in the Polish Lowland in the coastal zone of the South Baltic, covering the hydrogeological, hydrological and hydrobiological issues. The results indicate that the springs are fed from the Quaternary aquifer, in which three hydrostructural zones were distinguished. The third zone (III) with the largest area and water resources is of crucial importance in the recharge of the springs. The yield of the springs is relatively high for young glacial areas, and in summer exceeds 70 dm⁻³·s⁻¹. The Roztoka Springs have a much larger underground recharge area than it is apparent from the topographic course of the watershed. Bicarbonates dominate the chemical composition of the springs. The primary type of water is calcium-bicarbonate-sulphate. The vegetation corresponds to the difficult environmental conditions and is represented primarily by the Montio-Cardaminetea group. The Roztoka Springs area represents high landscape values. This is why it should be recommended for protection in order to preserve its natural condition, which is threatened by current forest management.

尚未令人满意地认识到欧洲低地的温泉的发生。这是因为脑病学研究主要集中在山区，那里的泉水很普遍，并且水源丰富。对波兰的低地和冰川后地区的温泉进行研究的前提是，它们可以评估地质结构和水文条件与山区不同的地区的春季丰度，这是一个极为重要的论据。该研究报告提出了对位于南波罗的海沿岸波兰低地的罗兹托卡温泉的初步研究结果，涉及水文地质，水文和水生生物学问题。结果表明，春季是从第四纪含水层注入的，其中区分出三个水力构造区。具有最大面积和水资源的第三区（III）在补给泉水中至关重要。对于年轻的冰川地区，春季的产量相对较高，夏季超过70 dm⁻³ ·s ^-1。罗兹托卡温泉的地下补给区比分水岭的地形路线明显大。碳酸氢盐支配着弹簧的化学成分。水的主要类型是碳酸氢钙硫酸盐。植被与艰难的环境条件相对应，主要由Montio-Cardaminetea组代表。罗兹托卡温泉地区代表着很高的景观价值。这就是为什么应该建议对其进行保护，以保持其自然状况，而目前的森林经营正威胁着这种状况。
