Long term change in phytoplankton assemblage as an indicator of environmental change in a heavily impacted coastal bay – Jiaozhou Bay in China
Over the past decades, the coastal environment in China has been greatly modified by the rapid economic development and heavily human activities. Jiaozhou Bay, a semi-enclosed basin in the western Yellow Sea of China, will be presented as a typical case in this talk. For example, the population around Jiaozhou Bay increased from 4.6 million to 7.0 million during 1960s-1990s; the waste water discharge increased from 146×106 t in 1988 to 185×106 t in 1997; the aquaculture increased from 540 t/y in 1980 to 81,000 t/y in 1995. Phytoplankton as one of ecological indicators was used to reflect these environmental changes in Jiaozhou Bay. The results of phytoplankton data from 1954-2004 in situ combined with the evidence of diatom debris in a 100 year sediment core indicated a shift in the dominant species, cell size change and decrease in abundance. The related chemical and physical parameters (nutrient, temperature etc.) and human activities will be explored for understanding the response of the phytoplankton assemblage to the environmental change.
