Abstract The paper presents the results of the analysis of diatoms from surface sediments (stones, sands) and macroflora (seagrass, macroalgae) collected at 16 sampling sites located along the inner coastal zone of Puck Bay (southern Baltic Sea) along the Hel Peninsula. The main diatom species of epilithon, epipsammon and epiphyton were characterized with respect to their autecological preferences (habitat, salinity, trophic status, saprobity). Three groups of diatoms were distinguished with respect to the type of substrate based on the results of benthic flora analysis: diatoms (i) of one type of substrate, (ii) of two types and (iii) those occurring on all types of substrates. Moreover, the distribution of benthic diatom communities indicates ecological differences in the study area. Marine and brackish-water species were observed in large numbers in the coastal zone of the Outer Puck Bay, whereas freshwater flora occurred with a higher frequency in the coastal zone of the Puck Lagoon. The content of polysaprobionts and of α-mesosaprobionts indicates that the region of the Hel Tip is highly eutrophicated and very polluted. The coast in the vicinity of Kuznica is less polluted, whereas the best environmental conditions are found in the Jurata–Jastarnia region, as evidenced by the frequency of diatoms that are β-mesosaprobionts.

帕克湾(波罗的海南部)沿海地区海底硅藻群的生物多样性:以赫尔半岛为例

摘要 本文介绍了对位于赫尔半岛帕克湾(波罗的海南部)内海岸带的 16 个采样点收集的表层沉积物(石头、沙子)和大型植物群(海草、大型藻类)中的硅藻的分析结果。附生、附生和附生的主要硅藻种类的特征在于它们的自身生态偏好(栖息地、盐度、营养状态、腐烂性)。根据底栖菌群分析的结果,根据底物类型区分了三组硅藻:硅藻 (i) 一种底物,(ii) 两种类型和 (iii) 发生在所有类型底物上的硅藻。此外,底栖硅藻群落的分布表明了研究区的生态差异。在外帕克湾沿海地区观察到大量海洋和半咸水物种,而在帕克泻湖沿海地区出现的淡水植物群出现频率较高。polysaprobionts 和 α-mesosaprobionts 的含量表明 Hel Tip 区域高度富营养化和污染严重。Kuznica 附近的海岸污染较少,而 Jurata-Jastarnia 地区的环境条件最好,这可以从作为 β-中生菌的硅藻的频率来证明。
