外文摘要：A POM08 model with a wetting and drying scheme was applied to simulate the twodimensional and vertical-averaged tide and tidal current of Zhanjiang Bay. Meanwhile, a two-dimensional material transport equation was coupled with the model, and the nitrogen and phosphorus environmental capacity of 17 pollution sources of the bay was calculated by using sharing rate method. The computed hydrodynamic results agreed well with the observed ones. The environmental capacity results showed that, there were no status capacity of almost all pollution sources, and a strict emission control should be performed to reduce the pollution. It was recommended that a proper emission control of nitrogen should be carried out in 8 pollution sources including Suixi river, Zhanjiang power plant outlet, etc., and a proper emission control of phosphorus should also be carried out in the rest 15 pollution sources except for foreign trade wharf sewage outlet and Dongshen shrimp sewage outlet. ? 2015 Taylor & Francis Group, London.
