主　　题：TPLC environmental capacity COD Luoyuan Bay linear programming model 

摘      要：The rapid economic and social developments in the Luoyuan and Lianjiang counties of Fujian Province,China,raise certain environment and ecosystem *** unusual phytoplankton bloom and eutrophication,for example,have increased in severity in Luoyuan Bay （LB）.The constant increase of nutrient loads has largely caused the environmental degradation in *** countermeasures have been implemented to solve these environmental *** most effective of these strategies is the reduction of pollutant loadings into the sea in accordance with total pollutant load control （TPLC） plans.A combined three-dimensional hydrodynamic transport-transformation model was constructed to estimate the marine environmental capacity of chemical oxygen demand （COD）.The allowed maximum loadings for each discharge unit in LB were calculated with applicable simulation *** simulation results indicated that the environmental capacity of COD is approximately 11×l0^4tyear^-1 when the water quality complies with the marine functional zoning standards for LB.A pollutant reduction scheme to diminish the present levels of mariculture-and domestic-based COD loadings is based on the estimated marine COD environmental *** obtained values imply that the LB waters could comply with the targeted water quality *** meet the revised marine functional zoning standards,discharge loadings from discharge units 1 and 11 should be reduced to 996 and 3236t year^-1,respectively.
