摘要

Abstract

To understand the relationship between the plankton community and environmental factors and water quality in the Bayuquan Port of Liaodong Bay

China

and investigations were carried out during six different periods (April 2009

April 2010

October 2011

April 2012

October 2012

and April 2013). This area was characterized by high levels of nutrient and suspended solids (SPS) during survey periods

and eutrophication led to the occurrence of red tides in April and October 2012 and April 2013. Our analyses revealed that the plankton communities of Bayuquan Port lacked stability and were affected seriously by external disturbance (e.g.

oceanographic engineering and river runoff). Our data indicate that oil

dissolved inorganic nitrogen (DIN)

SPS

and chlorophyll a (Chl-a) were key factors that regulated the phytoplankton and zooplankton communities. The partial redundancy analysis (partial RDA) suggested that oil and SPS were the most important environmental variables affecting the phytoplankton community in April 2010 and 2012

whereas DIN concentration played a governing role in zooplankton dynamics. Oil and Chl- a concentrations affected significantly the zooplankton community in October 2012. Therefore

the plankton communities could reflect both dynamic changes in coastal environmental factors and the ongoing eutrophication process caused by anthropogenic activities in this area.
