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