Investigation of Net-Phytoplankton Community Structure in Liaodong Bay in Spring of 2009
摘要
Abstract
The species composition, distribution of cell abundance, community diversity and similarity of net-phytoplankon in Liaodong Bay in spring （May） of 2009 were analyzed. A total of 32 taxa which belong to 23 genera of 3 phyla were identified in the survey area. The majority of species were neritic and cosmopolitan in tem- perate coastal seas, while the minority were oceanic warm water or oceanic species. The phytoplankton community was mainly composed of Bacillariophyta and Dinophyta. The dominant species include Noctiluca scientillans, Proboscia alata, Chaetoceros curvisetus, Coscinodiscus gigas and Pseudo-nitzschia pungens etc. The cell abun- dance of net-phytoplankton was nonuniform and the horizontal distribution showed a decline trend from the coastal areas to the center of the bay. The Shannon-Wiener index and Pielou evenness index were low and the community structure was unsteady. The result of cluster analysis indicated that the phytoplankton community similarity was relatively high.关键词
