摘　　要：对溶解无机氮（DIN）容量总量控制实施的具体原理和方法进行了研究。1979～2005年渤海DIN排海通量总体上呈“N”形变化趋势,年均入海通量34×10^4t/a。基于多介质海洋环境中的迁移-转化箱式模型,推算出在Ⅰ类、Ⅱ类、Ⅲ类和Ⅳ类海水水质标准下渤海DIN极小海洋环境容量分别为（22,29,38,47）×10^4t/a。分配容量优化结果表明,在在国家Ⅰ类、Ⅱ类海水水质标准条件下,2010年辽宁、河北、天津和山东三省一市DIN排放量均超过其最大允许排放量,均需不同程度的削减,平均削减预计排放量的37%和29%。The principle and method of gross control of dissolved ioorganic nitrogen（DIN） environment capacity in the peripheral zone of the Bohai Sea were studied. The results show that the flues of DIN into the Bohai sea present an N-shape with an annual flux of 34×10^4 t/a from 1979 to 2005. The minimal marine environmental capacities of DIN under the State Seawater Quality Standards estimated according to the transfer and transformation model in the multimedia marine environment are 22× 10^4 t/a for Grade Ⅰ, 28×10^4 t/a for Grade Ⅱ, 38×10^4 t/a for Grade Ⅲ, and 47×10^4 t/a for Grade Ⅳ, respectively. The optimized results of the allocation capacity model show that the discharge amount of DIN exceeds its environmental capatity under Grades Ⅰ and Ⅱ of the State Seawater Quality Standards and the average cut rates are 37 % and 29 % respectively in 2010.
