摘　　要：基于三维斜压水动力和水质模型,以我国1970年代未污染调查资料为背景,用AR-CINFO提取出渤海的各参量的初始场,较准确地模拟了1978年整个渤海及北黄海海域表层COD迁移、降解及沉降的过程,为以后对渤海的短期及长期水质诊断和预报研究工作奠定了基础。A Three-dimensional hydrodynamic and water quality models are developed. The initial COD distribution is based on the pollution survey at the end of 1970＇s and all the relative parameters are obtained by ARCINFO and interpolated into the whole computed do- main. The processes of transport, degradation, and deposition of COD in Bohai Sea and North Yellow Sea in 1978 are simulated. The work establishes a model which can be used to improve for further water quality diagnose and prediction for Bohai Sea.
