Abstract

Based on the ship-based data in the Lianzhou Bay, an advection-diffusion model of pollution is established. The sharing coefficient field (SCF) and the responding coefficient field (RCF) are simulated by this model. The environmental captivity (EC) is calculated by the simplex method according to the water quality standard. Results showed that that for seawater of Grades I to IV (according to the National Standard), the annual ECs of DIN in the Lianzhou Bay were 374.13 tons, 553.04 tons, 1015.57 tons, and 1181.60 tons, respectively, and those of DIP were 24.36 tons, 62.24 tons, 62.24 tons, and 212.44 tons, respectively, and the annual ECs of COD were 4147.37 tons, 7918.38 tons, 12770.30 tons, and 16914.99 tons, respectively. According to the Beihai water standard quality, the annual ECs of DIN, DIP and COD were 805.79 tons, 103.45 tons, and 9902.54 tons, respectively. The results of this study provide an evidence for the management of marine environment quality and the total mass control of pollutants in the Lianzhou Bay.
