Correlation of photoplankton and its environmental factors in Rushan bay

Abstract

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.

Key words: Photoplankton, Environmental factors, Correlation
