ENVIRONMENTAL FACTORS AFFECTING CHLOROPHYLL-a CONCENTRATION IN THE BOHAI BAY
2006年渤海湾赤潮监控海域叶绿素-a的影响因子分析研究

On the basis of observed data in the Lüju River red tide monitoring area of the Bohai Bay during the summer of 2006, the correlations between physical, chemical, meteorological factors and chlorophyll-a were analyzed. It was shown that the phosphate, silicate, dissolved oxygen and pH had a close relationship with the concentration of chlorophyll-a. The multivariate regression analysis showed that the main factors affecting the concentration of chlorophyll-a in the Bohai Bay were phosphate and dissolved oxygen. This study was helpful in developing statistical and ecosystem model for chlorophyll-a prediction in the Bohai Bay.
