Rushes belong to the group of plants commonly found in water bodies, fulfilling many important functions. However, their presence depends both on features of the immediate surroundings and morphology of the lake. At the same time, rush presence can be an indicator of important features of the surrounding habitats. The aim of this study was to determine the impact of shoreline and buffer zone development on the attributes of rushes. Indications of lake features affected the rushes most strongly. We analysed 65 lakes located in the eastern part of Poland, within the boundaries of the Łęczna-Włodawa Lake District. The multidimensional analyses identified factors that most strongly determined the development of lake rushes in Polesie Lubelskie. The presence of peat bogs, scrubland communities, and wet meadows favoured the development of rushes. Among the morphometric characteristics of lakes, the depth and frequency of water mixing were significant, as well as the trophic level of the lake. Moreover, models describing scenarios for further development of rushes were developed. They predicted that the surface area of the rushes in the lake will increase (average of 0.288 ha) when the peatlands become overgrown 1 ha, and the share of dry (drained) meadows will increase (average of 0.996 ha) in the buffer zone. The increase in the density of rushes will take place if the share of buildings and scrub communities increases both in the buffer zone and shoreline area.

灯芯草属于水体中常见的植物群，具有许多重要的功能。然而，它们的存在取决于周围环境的特征和湖泊的形态。同时，灯心草的存在可以作为周围栖息地重要特征的指标。本研究的目的是确定海岸线和缓冲区开发对灯心草属性的影响。湖泊特征的迹象对灯芯草的影响最为强烈。我们分析了位于波兰东部、Łęczna-Włodawa 湖区边界内的 65 个湖泊。多维分析确定了最有力地决定卢布林省湖沼发展的因素。泥炭沼泽、灌木丛群落和潮湿草甸的存在有利于灯心草的发展。湖泊的形态特征中，水体混合的深度和频率以及湖泊的营养级具有显着性。此外，还开发了描述灯心进一步发展情景的模型。他们预测，当泥炭地杂草丛生 1 公顷时，湖中灯心草的表面积将增加（平均 0.288 公顷），缓冲区内干燥（排水）草甸的份额将增加（平均 0.996 公顷）。如果缓冲区和海岸线区域的建筑物和灌木丛群落的比例增加，灯心草的密度就会增加。他们预测，当泥炭地杂草丛生 1 公顷时，湖中灯心草的表面积将增加（平均 0.288 公顷），缓冲区内干燥（排水）草甸的份额将增加（平均 0.996 公顷）。如果缓冲区和海岸线区域的建筑物和灌木丛群落的比例增加，灯心草的密度就会增加。他们预测，当泥炭地杂草丛生 1 公顷时，湖中灯心草的表面积将增加（平均 0.288 公顷），缓冲区内干燥（排水）草甸的份额将增加（平均 0.996 公顷）。如果缓冲区和海岸线区域的建筑物和灌木丛群落的比例增加，灯心草的密度就会增加。
