Spatial distribution of plant communities in the human-modified aquatic ecosystem within the Dnieper–Bug Estuary is marked by discrete-continuous patterns. Continuity is caused by hydrological interconnection between the subsystems, and discreteness — by habitat diversity. For higher aquatic plants, the continuity aspect consists in overgrowth of emergent plants all-round the shoreline in both subsystems. The discreteness aspect is noticed in presence of floating-leaf plants’ and submerged plants’ belts in the natural subsystem only (the lake) and their absence in the artificial one (the sand quarry). For algal communities, continuity is observed in predominance of the same divisions in both subsystems. Discreteness manifests itself in higher taxonomic and floristic diversity of algae in the natural subsystem, than in the artificial one. The process of hydrological interaction between phytoplankton and epiphytic algae is another important mechanism sustaining continuity of algal communities.

在第聂伯河—布格河口内人类修饰的水生生态系统中植物群落的空间分布以离散连续模式为特征。连续性是由子系统之间的水文互连和离散性（由栖息地多样性）引起的。对于高级水生植物，连续性在于两个子系统中遍布海岸线的新兴植物的过度生长。离散性方面仅在自然子系统（湖泊）中存在浮叶植物和淹没植物的带，而在人工区域（沙石场）中则没有。对于藻类群落，在两个子系统中相同分区的优势中观察到了连续性。离散性表现为自然子系统中藻类的分类学和植物学多样性高于人工子系统。
