Abstract
Aimed at the hot point of the eutrophication of culture water and according to the research on dynamic model,the distributions and variations of DIN and DIP,controlling mechanisms and the influences on environment in Jiaozhou Bay are analyzed.The results show that the values of DIN and DIP caused by the scallop cultivation are only 8% of that from the rivers in Jiaozhou Bay,but the concentrations of pollutants in culture areas are clearly higher than that of the central and the channel areas.So,the scallop cultivation can bring the serious environmental effects in local culture areas.
