摘　　要：将渤海分为莱州湾、渤海湾、辽东湾和渤海中部4个不同区域,讨论了在水交换作用下渤海水域污染面积与污水排放量的相关性,建立了渤海海域污染物累积量的计算方法,对渤海承载排污的能力进行了分析。结果表明:在陆源污染物排放以一定增长率逐年增加的情况下,渤海海域的纳污承载力为230~278亿t左右,其中莱州湾海域的纳污承载力为62~63亿t左右,渤海湾海域为40~41亿t左右,辽东湾海域为44~52亿t左右。文中的分析方法对于判断和预测海洋资源环境承载能力具有借鉴意义。The correlation between polluted area and sewage discharge in Bohai sea area under water exchange is discussed. The calculation method for the accumulation of contaminants in Bohai sea is established and the Bohai Sea bearing capacity is analyzed from four different regions: Laizhou Bay, Bohai Bay, Liaodong bay and central Bohai. The result shows that: under the circumstance that the terrestrial sewage discharge is increasing year by year with certain growth rate, the pollutant bearing capacity of the Bohai Sea is about 23~27.8 billion tons of sewage discharge. There are about 6.2~6.3 billion tons of pollution bearing capacity in the waters of Laizhou bay, about 4.0~4.1 billion tons in Bohai bay, and about 4.4~5.2 billion tons in Liaodong bay. The analysis method is useful for judging and predicting the pollutant bearing capacity of marine resource environment.
