英文摘要	运用一、二维耦合模型,考虑季节性风生海流和潮流的作用,对开凿胶莱运河改善渤海水质的效果进行了初步研究。以海水半交换周期和运河的净流量为衡量的主要指标,进行四种运河规模的模拟实验,评估各种开渠规模治污的效益。模拟结果显示,开凿运河后,运河的流向随潮汐过程变化,但能够形成少量由胶州湾向莱州湾的净流量,通过运河的年净流量与运河规模成正比,为渤海海峡年过水量的1‰—2.5‰。运河规模达到5000M(宽)x20M(深),海水半交换周期仅缩短3%。因此,开凿胶莱运河改善渤海水质的效果不明显,渤海污染治理的关键应该是污染源头控制和管理。; In consideration of tide and seasonal sea surface wind,numerical simulation in 1-D and 2-D grid was performed on water exchange via the Jiaolai Canal,a proposed canal that would cut through Shandong Peninsula and link directly the Laizhou Bay and the Jiaozhou Bay,for solving the pollution problem in the Laizhou Bay.Two indexes were used to evaluate the water exchange capacity,the half-life time of the Bohai Sea water in canal and the net flux of canal,in four canal sizes.The result shows that due to tide effect,the flow direction in the canal would flow back and forth;and only a little net flux could go through the canal,which accounts for only 1‰—2.5‰ of the flux of the Bohai Strait.The half-life time of the Bohai Sea would be shortened for about 3% in the case of the largest canal size at 5000m(width)× 20m(depth).Therefore,the creation of the Jiaolai Canal would not be able to solve the pollution;instead,controlling pollution source is strongly suggested.; 国家自然科学基金资助项目;40676066号;国家高技术研究发展(863)计划资助项目“区域性海洋监测系统项目——子项目海上突发事件应急辅助决策系统”;2008—2011
