Abstract

Ye, Y.; Chen, K., and Huo, Y., 2019. Long-term change of environment and it's influence on phytoplankton community structure in Daya Bay. In: Hoang, A.T. and Aqeel Ashraf, M. (eds.), Research, Monitoring, and Engineering of Coastal, Port, and Marine Systems. Journal of Coastal Research, Special Issue No. 97, pp. 191–197.

Based on the phytoplankton samples in Daya Bay from 2004 to 2016, the data of environmental factors were collected simultaneously to analyze the long-term changes of environmental factors and their effects on phytoplankton community structure. Our results showed that nutrient concentration in Daya Bay increases year by year, which was caused by the rapid economic development around Daya Bay and a large amount of industrial and agricultural wastewater and domestic sewage discharged into the water. As a result, the concentrations of nitrogen and phosphorus in Daya Bay were much higher than the growth threshold of phytoplankton. Therefore, the change of environmental factor has an important impact on the community structure of phytoplankton in Daya Bay. The dominant species had obvious succession in Daya Bay, and the species that preferred fertilizer increased significantly and became the dominant species.
