| 英文摘要 | To better understand the spatial variations in phytoplankton abundance and community structure and their relationship with environmental parameters in Jiaozhou Bay, Yellow Sea, in Shandong, East China, observations were conducted to estimate abundance of net-phytoplankton and key groups along with environmental parameters in three typical sites in seasonal survey from 2004 to 2016 in the bay. The spatial patterns of phytoplankton abundance differed obviously between the inner and the outer bay. The abundance of total phytoplankton and diatoms increased obviously in the northern part of the bay, while decreased in the southern part and outer bay. An increase in dinoflagellate abundance was obvious in the outer bay. Variations in the dynamics of phytoplankton abundance could be largely explained by the succession of chain-forming diatoms and dinoflagellates. The key chain forming diatom groups Chaetoceros and Thalassiosira increased markedly, especially in winter in the northern part of the bay, while in the southern part and the outer bay, Chaetoceros declined. Besides, the key dinoflagellate groups Ceratium and Noctiluca increased noticeably, resulting in a significant increase in the dinoflagellate/diatom ratio in the outer bay. These variations has a significant correlation with environmental variables of surface seawater temperature, phosphorus, nitrogen, salinity, and N/Si ratio (P<0.05). For the key groups, temperature was the primary driver of dinoflagellate abundance, while the N/P ratio was critical for chain-forming diatoms. The abundance of phytoplankton showed a clear spatial pattern and associated obviously with environmental factors in the marine ecosystems, offering insights into coastal ecosystem management and conservation strategies. |
