摘要
针对养殖水体富营养化这一环境热点问题,通过建立的三维水质模式对胶州湾扇贝养殖所产生的N、P污染物的分布规律、输运过程以及对环境的影响进行了研究。结果表明,尽管胶州湾扇贝养殖对无机营养盐的贡献只占到河口陆源输入的8%左右,但由于沿岸养殖区的潮流较弱,不利于污染物质的输移和扩散,给养殖局部海域环境带来较大影响。
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.
