Temporal and Spatial Characteristics of Phytoplankton Community and Health Assessment of Tangdao Bay Wetland Park
In order to understand the phytoplankton community structure and its temporal and spatial variation characteristics of Tangdao Bay wetland park,the phytoplankton was sampled from November 2022 to summer 2023,and quantified and identified by Algae-Hub.The results showed that a total of 117 species of phytoplankton belonging to 9 phyla and 76 genera were sampled during the investigation,including 69 Bacillariophyta,19 Chlorophyta,12 Cyanophyta,etc.The communities in spring and autumn were dominated by diatoms Skeletonema costatum,While the richness and density peaked in summer.Based on the statistics of diversity indices,there was no significant difference among the sampling sites in the same season.However,the seasonal variation of the phytoplankton was significant,especially between summer and two other season.Shannon-Wiener index and Pielou evenness index indicated that the water condition of Tangdao Bay was in a healthy condition.The phytoplankton community can maintain high primary productivity and inhibit the outbreak of red tide through intraspecific and interspecific competition.
