The distributions of the phytoplankton and their impacting factors in the Daya Bay in autumn 2011 and in spring 2012

Abstract

Abstract: This study was carried out in the Daya Bay in October 2011 and April 2012. Based on the data collected from 12 stations, phytoplankton taxonomic composition, abundance, dominance species and their impacting factors were examined. Surfer 8.0 software was used for drawing and illustrating, while SPSS 17.0 software was used for analyzing principal component factors (PCA). At the same time, it used multiple stepwise regression analysis method, and principal component scores as explanatory variables, aiming at studying the effect of environmental factor for phytoplankton abundance and picking out the main factors which influenced the distribution of phytoplankton in the Daya Bay. Furthermore, its distribution characteristics and the correlation with environmental factors were discussed. A total of 51 species (4 phyla, 31 genera) were identified. Among those species, Bacillariophyta is the dominant species, Pyrrophyta is subdominant species, and Xanthophyceae and Chromophyia are even rarely. The dominant species are Heterosigma akashiwo、Skeletonema costatum、Rhizosolenia setigera、Nitzschia pungens、Thalassionema nitzschioides in autumn, and Ceratium furca、Prorocentrum minimum、Ceratium fusus、Ceratium tripos in spring. The abundance of phytoplankton range from 1.56×10⁴ to 8.03×10⁴ cell/dm³ and the average value is 3.95×10⁴ cell/dm³ in autumn and range from 1.21×10⁴ to 4.70×10⁵ cell/dm³ and the average value is 7.84×10⁴ cell/dm³ in spring. Temperature、pH、PO^3-₄-P and TP are the main factors influencing the distribution of phytoplankton in the Daya Bay.

Key words: phytoplankton, abundance, distribution features, Daya Bay
