Study on the Phytoplankton Community Structural Features in Anhui Jieshou Liangwan National Wetland Park
In order to study the phytoplankton community structural features in Anhui Jieshou Liangwan National Wetland Park and their influencing environmental factors,4 sampling surveys were made in May,August and October 2023 and January 2024 respective-ly.The results showed there are a total of 101 identified phytoplankton species belonging to 60 genera in 8 phyla,in which Chlorophyta had the most identified species of 54,followed by Bacillariophyta with 24 species and Cyanophyta with 12 species.The main dominant species include Chlorella vulgaris,Scenedesmus quadricauda,Kirchneriella obesa of Chlorophyta,Phormidium tenue,Chroococcus mi-nor,Merismopedia minima,Melosira granulate of Bacillariophyta,Synedra acus,Cyclotella meneghiniana,Cyclotella spp.of Cyanophyta,etc.The phytoplankton community showed significant seasonal differences,most thriving and prolific in summer and least thriving in winter when the temperature was low.RDA results indicated that temperature,conductivity,turbidity,pH,and water depth were the key influencing factors on the phytoplankton abundance.Mantel analysis showed that temperature had significant effects on all the 4 major phytoplankton species and was the key factor affecting phytoplankton abundance.The study is to provide basic data for future conservation and restoration of the park.
