摘　　要：对1996～2000年间，大连市化肥农药使用现状进行了统计分析，运用不同类型有机物理论化学耗氧量的数学计算模型，分别计算了大连市化肥农药流失和工业废水排放对海域的污染影响，结果认为大连市化肥农药流失对海域污染物COD的污染贡献率远远大于工业废水排放的COD贡献率。最终提出应采取加强化肥农药使用管理等有效手段防治近岸海域化肥农药流失污染。In this paper, the statistical data on the utilization of the fertilizer and pesticide in Dalian from 1996 to 2000 have been analyzed and discussed. Based on the different COD calculation module with multiple organic theory, the effects of pollution in the sea area caused by the fertilizer leaching and runoff and the industrial wastewater were made, respectively. COD pollution contribu- tion of the fertilizer leaching and runoff is far more than the industrial wastewater. Therefore, some effective countermeasures, such as strengthening the fertilizer and pesticide management etc. were proposed for preventing the sea polluted by the leaching and runoff of the fertilizer and pesticide.
