title: [Correlation of photoplankton and its environmental factors in Rushan Bay].
abstract: The relationship between photoplankton and its environmental factors in Rushan Bay was studied from June to September, 1995. The result shows that there existed a negative correlation between the number of photoplankton and the content of inorganic nutrients. The correlation coefficients for inorganic nitrogen and phosphorus were -0.67 and -0.80, respectively. The dissolved oxygen and chlorophyll-a were positively correlated to photoplankton, and their correlation coefficients were 0.92 and 0.85 respectively. Based on N/P analysis, the content of inorganic nitrogen was relatively short to the reproductive growth of photoplankton during experimental months, except for the last ten days of August.
