黄河口及邻近海域浮游植物群落分布特征及与水环境的关系
Distribution of Phytoplankton Community and Its Relationship with Water Environment in the Yellow River Estuary
摘要
Abstract
Based on the phytoplankton and water environmental data collected from the surveys in May and August of 2011 to 2014 in the Yellow River Estuary and its adjacent waters,this study discussed the relationship between the spatial distribution of phytoplankton community and water environment.The result showed that 108 species which belong to 46 genera of 3 phyla were indentified,among these species,85 were members of Bacillariophyta,22 Pyrrophyta,and 1 Chrysophyta,accounting for 78.7％,20.4％ and 0.9 ％ of the total phytoplankton species,respectively.The abundance of phytoplankton in May (2.29 × 107 cells/m3) was far less than that in August (6.83×108 cells/m3).The Shannon-Winner Index (H') was 1.79 and 2.39 in May and August.The phytoplankton community and water environment was divided into two zones with significant differences by cluster analysis (p＜0.01):the northern and eastern offshore area (group Ⅰ) and the southern coastal waters (group Ⅱ).In May,the T,pH,N ∶ P and COD in group Ⅰ were significantly lower than that in group Ⅱ (p＜0.05),while the Depth and DO were significantly higher than that in group Ⅱ (p＜0.05),the dominant species of group Ⅰ were Rhizosolenia stolterfothii,Coscinodiscus sp.,Paralia sulcata (Ehrenberg)Cleve and Rhizosolenia alata f.indica Hustedt,the dominant species of group Ⅱ were Rhizosolenia stolterfothii and Coscinodiscus sp.In August,the Depth,S and SD in group Ⅰ were significantly higher than that in group Ⅱ (p ＜0.05),and DIN,COD and TPH were lower than that in group Ⅱ (p＜0.05),the dominant species of group Ⅰ were Chaetoceros pseudocurvisetus Margin,Thalassionema frauenfeldii,Chaetoceros curvisetus and Chaetoceros spp.,and the dominant species of group Ⅱ were Chaetoceros debilis,Chaetoceros curvisetus,Skeletonema costatum,Coscinodiscus sp.,Chaetoceros laciniosus,Chaetoceros pseudocurvisetus Margin and Thalassionema frauenfeldii.The results of redundancy analysis between the abundance of phytoplankton dominant species and water environment showed,the key environmental factors influencing the distribution of phytoplankton dominant species were T,pH and COD in May,S and COD in August.关键词
