Abstract

Phytoplankton community structure and environmental factors of Jiaolai Estuary and adjacent waters in Laizhou Bay were investigated in October, 2015. Affected by high-concentration salt-containing wastewater discharged in east coasts, the water quality of investigated waters showed a trend of high salinization. 17 genera and 25 species were authenticated and diatom dominated. Phytoplankton species and abundance decreased obviously compared with those in the same period of previous years and the trend of change was increasing from the estuary and coasts to the outside, which was in contrast with distribution characteristics of phytoplankton in typical estuarine coastal waters. In addition to the nearshore alga species such as Melosira sulcata, offshore high-salt specie Cos. asteromphalus also became one of the dominant species in investigated waters. Results of multivariate statistics divided the phytoplankton community into three ecological groups, including Group I of an estuarine type in Jiaolai Estuary, Group II of a coastal low-salt type in east coasts of Jiaolai Estuary, and Group III of a high-salt, low-nutrition type near the main drain outlets of the industrial park. Correlation analysis showed that salinity and transparency were the main factors affecting the phytoplankton community composition of the investigated sea area.
