| 摘 要： | 为了解日照近岸海域浮游植物的群落结构及其环境影响因子,于2016年2月和8月对该海域18个站位进行了浮游植物种类和优势种组成、丰度、群落多样性及其环境因子调查分析,利用CLUSTER聚类分析、MDS排序和Pearson相关分析探讨该海域浮游植物群落结构和环境因子的关系。调查海域共鉴定浮游植物3门41属92种,其中,硅藻门(Bacillariophyta)31属73种,甲藻门(Pyrrophyta)9属18种,金藻门(Chrysophyta)1属1种。冬季主要优势种为柔弱几内亚藻(Guinardia delicatula),夏季主要优势种为劳氏角毛藻(Chaetoceros lorenzianus)和深环沟角毛藻(Chaetoceros constrictus)。冬季浮游植物丰度为2.20×106~6.12×107cells/m3,夏季丰度为3.75×104~5.70×106cells/m3。Pearson相关分析表明影响浮游植物丰度的环境因子为盐度、水深、溶解氧(DO)、硝酸盐、亚硝酸盐、铵盐、总氮和重金属中的锌。在日照近岸海域,相比Shannon-Wiener多样性指数(H')分析方法,多元统计分析能更好地反映该海域的水环境质量状况。

| Abstract: | To understand the features of phytoplankton communities and their main impact factors, two cruises were conducted in the coastal waters of Rizhao in February and August 2016.Phytoplankton species and dominant species composition, abundance, community diversity and environmental factors were analyzed, and the cluster analysis, multi-dimentional scaling (MDS) ordination techniques, PearsonScorrelativeSanalysis were applied in this study to reveal the relationship between phytoplankton community structure and environmental factors. In total 92 taxa were identified, which belong to 41 genera and 3 phyla. Among which 73 were diatoms,18 were dinoflagellates,1 was chrysophytas. The dominant species was Guinardia delicatula in winter , and Chaetoceros lorenzianus , Chaetoceros constrictus in summer.The cell abundance of phytoplankton ranged from 2.20×106 -6.12×107 cells/m3 with an average of 2.61×107 cells/m3 in winter and from 3.75×104 -5.70×106 cells/m3 with an average of 1.22×106 cells/m3 in summer.Pearson correlation analysis showed that salinity, depth of water, dissolvedSoxygenS(DO), nitrates, nitrite, ammonium salt, total nitrogen, heavy metal (Zn) inStheSseaSwater had the greatest influence on abundance of phytoplankton.Compared with Shannon Wiener diversity index (H ") method, multivariate statistical analysis could better reflect the water environment quality in the coastal waters of Rizhao. |
