Hyporheic water exchange driven by groundwater-surface water interactions constitutes habitat conditions for aquatic biota. In our study, we conducted a field-research-based analysis of hyporheic water exchange to reveal whether the hyporheic water exchange differentiates particular Ranunculus sp. habitats. We measured the density of the stream of upwelling and hydraulic gradients of water residing in the hyporheic zone in 19 Polish rivers. We revealed that R. peltatus and R. penicillatus persist in habitats of considerably higher hyporheic water exchange upwelling flux (respectively 0.0852 m∙d∙m and 0.0952 m∙d∙m) than R. circinatus, R. fluitans, and a hybrid of R. circinatus × R. fluitans (respectively m∙d∙m; 0.0222 m∙d∙m and 0.0717 m∙d∙m). The presented results can be used to indicate aquatic habitat suitability in the case of protection and management of ecosystems settled by Ranunculus sp.
由地下水-地表水相互作用驱动的底水交换构成了水生生物的栖息地条件。在我们的研究中，我们进行了基于实地研究的底水交换分析，以揭示底水交换是否区分了特定的毛茛属植物栖息地。我们测量了 19 条波兰河流中上升水流的密度和位于底质区的水力梯度。我们揭示了，与 R. circinatus、R. fluitans 和 R. circinatus × R. fluitans 的杂种相比，R. peltatus 和 R. penicillatus 存在于底水交换上升通量明显更高的栖息地中（分别为 0.0852 m·d·m 和 0.0952 m·d·m）。所呈现的结果可用于指示毛茛属植物定居的生态系统的水生栖息地适宜性，以便在保护和管理时使用。
