摘要: Data collected from 12 stations in Daya Bay different seasons 2002 revealed the relation between water quality and phytoplankton response patterns. The results showed that could be divided into wet dry by multivariate statistical analysis. Principal component analysis indicated temperature, chlorophyll a nutrients were important components during season (summer autumn). salinity dissolved oxygen main environmental factors (winter spring). According to non-metric multidimensional scaling, there was shift large diatoms smaller line-chain taxa with condition of high inorganic nitrogen phosphorous concentration ratio. Nutrient changes can thus alter community composition biomass, especially near aquaculture farm areas. There no evidence an effect thermal nearby nuclear power plants on observed biomass 2002.
