通过对增养殖海区进行大量水质、底质和生物调查，阐明增养殖海区自身富营养化主要源于底泥污染。进行了水质、底质污染因子评价，并与生物评价取得了一致的结论。介绍了增养殖海区环保工作应进行的几个方面的工作和方法，着重指出海区环境容量研究对增养殖生产的持续发展具有重要意义。 Through a large number of aquaculture areas, water quality, sediment and biological surveys, clarified that the increased eutrophication of aquaculture mainly due to sediment pollution. The water quality and sediment pollution factors were evaluated, and the results were consistent with the biological evaluation. The work and methods that should be carried out in the environmental protection of aquaculture and marine areas are introduced. It is emphasized that the research on the environmental capacity of the sea areas is of great significance for the sustainable development of aquaculture.
